[ARCADE] Supermodel 0.3a SVN586

Daytona USA 2 - Battle on the Edge (SEGA, 1998)

Revision 584

Author: trzy | Date: 7 kwietnia 2017 06:42:04

• Harry Tuttle's fixes to fishing controls: invert fishing rod y and fishing stick y axis values so setting a negative axis is not necessary. Also changed reel to an analog input (similar to a pedal), whose neutral position is 0.

Revision 583

Revision 579

Author: dukeeeey | Date: 5 kwietnia 2017 19:57:38

• Daytona seems to use this completely undocumented feature of the real3d pro-1000, the ability to invert texture colours. This patch fixes the colours on the cars, and the signs which should flash by alternating their colours.

Revision 578

Author: trzy | Date: 5 kwietnia 2017 18:19:08

• Removed last vestiges of CINIFile from input system and removed Games.cpp, INIFile.cpp, and ROMLoad.cpp

• Using Game::INPUT_* instead of obsolete GAME_INPUT_*

Revision 576

• Added a stretch mode (-stretch) and modified new renderer's viewport code (hopefully correctly) to handle aspect ratio correction and widening the way the legacy one does.

Revision 724

Author: dukeeeey | Date: środa, 2 maja 2018 22:10:02

• Render the opaque part of texture transparency in the first pass. Fixes numerous transparency related issues in lemans24 and some in ocean hunter. I don't really know if this is the 'correct' way of solving this because the real3d pro-1000 is a complete black box. There is still a lot we don't understand about how it handles transparency.

update from svn 716

• correct dirtdvls upto 4 players (before, only 2 players was possible). However, the
• satellite doesn't work spikeout-spikeofe, should work, but using a hack in code, so it is not the normal way... dayto2pe normally works now (very slow related to no threads...)
• scud works a little but sadly with graphical bugs, and cars from other players rotates on their axis (it seems linked to player's direction)
• daytona2,sr2,lemans,von2 always doesn't work

Warning, do not mix the version without network and with network, it is about 2 very distinct versions. The exe is proposed on an experimental basis, you are warned Only 3 games do not work too badly dirt devils, harley davidson et skichamp

to test
create 2 different directories: 1 for the master and 1 for the slave
edit the supermodel.ini files and add:

for the master
EmulateNet=1
port_in = 1970
port_out = 1971
addr_out = "127.0.0.1"

for the slave
EmulateNet=1
port_in = 1971
port_out = 1970
addr_out = "127.0.0.1"

change the ip by your ip network, here is the local netloop to test on the same computer. I recommend starting with this netlocal loop 127.0.0.1.
Afterwards you can try between 2 computers
If pc1=192.168.0.1 and pc2=192.168.0.2 then master(pc1): addr_out = "192.168.0.2" (sending to pc2) et slave(pc2): addr_out = "192.168.0.1" (sending to pc1) with the quotation marks
Note the port inversion between master and slave, you can put any port you want.
In short, it looks like the config of model2, same principle

In each directory, you will also need to copy the normal version of supermodel. This will allow us to properly configure the network via the service menu
So type in command line as usual:
supermodel.exe name_of_the_rom

Enter the service menu and change the options for the network
your master to master
your slave to slave
do not forget to change the network ids (for example the master in 1 and the slave in 2)
save when leaving the service menu and leaving supermodel

now the proper network launch
the launch must be done exclusively on the command line
supermodel-net.exe -no-threads name_of_the_rom
Do not forget the -no-threads option because otherwise crash. This options will unfortunately slow down the emulator enormously while waiting for better.
Think about your firewall

Important information, the sync between master and slave may not be done correctly. If the games do not go into the attract mode or it seems blocked, it will be necessary to stop and restart, being careful to start the games in the same second (max 5 seconds). Additional constraint, impossible to pause, can not move the window once the connection is secured or else crash

Revision 680

Author: dukeeeey | Date: środa, 13 grudnia 2017 02:21:25

• Fix some bad/missing textures in fighting vipers. The game is referencing totally illegal texture sizes. The real h/w was just handling it somehow, whilst we were returning null for the textures. This might produce junk textures for the lower mipmaps, but this can be clamped in a later update.

Revision 679

Author: dukeeeey | Date: czwartek, 23 listopada 2017 18:51:51

• Shift fog maths to fragment shader to fix bug in virtua on.

Revision 678

Author: dukeeeey | Date: poniedziałek, 20 listopada 2017 23:21:15

• The vertex shader is run before clipping is done. If fogging values are calculated and clamped in the vertex shader it can interpolate bad values, since the range has been truncated. This happens if the polys overlap the near plane. The solution to clamp the values in the fragment shader. This fixes a bunch of fogging errors I long thought were transparency related errors in the ocean hunter.

• Makefile fixes: Moved Windows-specific source files out of Makefile.inc, using 'bin' and 'obj' when bits are not explicitly set, and changed output file to Supermodel rather than Supermodel.exe, which works on all platforms.

Revision 672

Author: dukeeeey | Date: 5 października 2017 21:15:00

• Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle)

• Get rid of unused variable warning

Revision 665

Author: dukeeeey | Date: 26 września 2017 02:30:08

• Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value.

Revision 647

Author: dukeeeey | Date: 6 września 2017 15:07:39

• Calculating the length of the vertex results in quite broken values for fogging when the vertices are traversing the view frustum. The hardware also wouldn't have been doing a square root per vertex for fogging. Simply using the z values is enough. Todo check clamping of values for the near/far planes.

• Optimise vertex data to cut down on unnecessary copying

Revision 644

Author: dukeeeey | Date: 29 sierpnia 2017 12:27:29

• Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions.

Revision 643

Revision 640

Author: dukeeeey | Date: 19 sierpnia 2017 22:06:31

• Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade.

Revision 636

Author: dukeeeey | Date: 16 sierpnia 2017 01:21:57

• Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading.

Revision 635

Author: dukeeeey | Date: 15 sierpnia 2017 22:50:36

• With fixed shading, when lighting is disabled, fixed shading appears to be a flat shaded version based upon the poly colour, instead of per vertex attributes.

• Fixed shading (per vertex poly colours) on step 1.5 hardware have the viewport ambient value added to them. This fixes various shading on scud. To do this had to switch the maths to the vertex shader.

Revision 630

• Fix attribute locations. glBindAttribLocation must be called linking

Revision 629

Author: trzy | Date: 11 sierpnia 2017 02:41:10

• Added support for loading shaders from files for new engine and tile renderer. Changed help text to reflect new engine being default.

Revision 628

Author: dukeeeey | Date: 10 sierpnia 2017 17:59:16

• make the new3d engine default :] Legacy engine can still be selected using -legacy3d in the command line

Revision 627

Author: dukeeeey | Date: 10 sierpnia 2017 17:43:03

• use generic vertex attributes

Revision 626

Author: dukeeeey | Date: 10 sierpnia 2017 01:25:01

• Technically matrix casts are only allowed in glsl 1.2 and later

• Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware.

Revision 622

Author: dukeeeey | Date: 3 sierpnia 2017 12:41:18

• Add the unclamped light model we know exists to the shaders.

Revision 621

Author: dukeeeey | Date: 2 sierpnia 2017 01:48:53

• Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway. Thanks to Harry for finding this bug :)

• We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model.

Revision 619

Author: dukeeeey | Date: 22 lipca 2017 19:15:14

• Implement unclamped light model based upon Harry's findings. Unknown how this is turned on/off.

Revision 618

Author: dukeeeey | Date: 8 lipca 2017 12:55:14

• Use c++11 raw string literals

Revision 617

Author: dukeeeey | Date: 29 czerwca 2017 21:05:30

• Clamp the ambient light to a max of 0.75. LA Machine guns seems to use an ambient value of 1, which is full bright for everything. But for some reason the hardware seems to treat this as ~ 0.75. This fixes various missing shading in the game. This doesn't seem to have any negative effects on other games I have tested. Clamping in the shader as we might need the full range of values for fixed shading.

Revision 616

• remove WIP code

Revision 615

Author: dukeeeey | Date: 25 czerwca 2017 21:50:02

• convert sun angle coordinate system outside of the shader

Ze względu na zmianę karty GFX (z ATI na Nvidia) trudno mi coś powiedzieć:P

Revision 614

Author: dukeeeey | Date: 21 czerwca 2017 19:04:53

• A second go at fixing the fixed lighting in star wars .. Fixed shading is per vertex poly colours. For some reason in star wars they are treated as unsigned values instead of signed, like in every other game. These polys are all marked with specular enabled, where as in the rest of the games they are missing this flag. That's the only difference I can find.

Revision 613

Author: dukeeeey | Date: 20 czerwca 2017 23:44:58

• fix double offset

Revision 612

Revision 610

Author: dukeeeey | Date: 17 czerwca 2017 18:05:54

• parse out some culling node values

Revision 601

Author: dukeeeey | Date: 15 kwietnia 2017 21:00:46

• There are 2 bits in the polyheader labelled discard. When both are set ie in sega rally, the polygons are totally discarded. Scud seems to set bit 1 which seems halve the opacity.

Revision 600

Author: dukeeeey | Date: 15 kwietnia 2017 01:41:11

• The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded.

• light parameters must be clamped (HarryTuttle)

Revision 597

Author: dukeeeey | Date: 12 kwietnia 2017 17:47:57

• Virtua fighter has a few massive polys that shouldn't be visible. It looks like these polys have a bad matrix, but the node distances are all zero. This means the bounding box that encapsulates them is of size zero. Skipping over these entirely seems to fix the issue.
