Altirra v2.60 test 4 [24.08.2014]
- UI: Added /portablealt:<file> switch to use alternate INI files.
- Notable changes:
- Overhauled the firmware UI a bit. When adding new firmware, the UI now asks for the type rather than relying on the selected category. CRC32 is also displayed for convenience.
- Fixed some issues with relative firmware paths. Note that any firmware detected under the program directory will be stored as a relative path, so if you are running Altirra in registry mode (non-portable) and have both instances scan the same folder under one of the instance's program folder, you can get duplicate entries. Don't do that.
- There is now an option to select default firmware per category. This allows multiple firmware images to be switched for types other than OS/BASIC without having to manually swap around paths.
- Added OS-B PAL to ROM autodetect list.
- Reworked BlackBox firmware handling so that both types of 16K ROMs are supported (1.xx) and 32K ROMs are now also supported (2.xx). The issue with 16K ROMs is that there are images with two different bank orderings out there, one with PBI device $01 at offset 0 and another with device $01 at offset $0800. This is now detected and adjusted for so that either order will work.
- Fixed BlackBox button handling. It was wired straight to IRQ but is now routed through the VIA.
- SCSI READ CAPACITY and IDENTIFY commands are now supported, so PARK.COM and HDFMT.COM now work.
- Device tree now saves, i.e. Computer -> BlackBox -> Hard Disk. Remember that you need to select the BlackBox entry to add the Hard Disk under it.
- /portablealt:<path> now launches portable mode with a different INI file. This needs to be specified each time, though.
- ATBasic updated to 0.96, now with fix for immediate mode repeat bug (also attached).
- Regarding some questions:
- ATBasic auto-repeat: Afraid I'll have to decline, for a couple of reasons. First, IMO the BASIC interpreter shouldn't enforce this since it's a user setting that may already have been changed. Second, doing this requires detecting the XL/XE OS, which will take additional code space.
- U1MB 65C816 visual glitch: This is due to DLI timing issues. Display list interrupts have very specific timing requirements that can easily be violated by a CPU accelerator. Accelerators vary widely in the strategy for dealing with this, if at all. One thing, though: if you're seeing this, it probably means you have the fast shadowed ROM enabled, and that's probably not realistic for U1MB which would be on the chip bus.

- MMU: Axlon banking register aliasing is now optional.
- Issue: The "NTSC Artifacting (Standard)" option appears to have broken between versions 2.60-test32 and 2.0.60-test33.
- Fixed -- it was 15 times too bright after the luma ramp change.

Altirra v2.60 test 40 [10.02.2015]
- Issue: Pressing the "menu" key on a 104(+) key keyboard. Using Altirra 2.60t39 on Windows 8.1 Pro 64-bit. Altirra 2.50 final also crashes with this as do both the 32 and 64 bit versions of both. Obviously an easy work around is just not press that key, but I have a feeling Avery would want to know that and mop that up.
- Menu key crash was just using the wrong window. Error 5 problem was due to a subtle issue when doing a direct putchar -- SDX expects ICAX1Z to be set, and because it wasn't, it was advancing the directory read pointer when writing to the file (!).

Altirra v2.60 test 39 [04.02.2015]
- Issue: The new XEP80 driver works better. There's an issue with it not handling keypresses though. It doesn't process BRK or Ctl+1 (pause) until an operation is complete. For example, copy a file to E: and if you press the Break key, after the listing is complete you get the Break Abort line.
- Yay, someone's using it! Fixes
- adds placeholders for BlackBox and MIO firmware.

- Devices: Added MidiMate emulation.
- Friend of mine handed me a bag of obscure hardware he pulled out of his ass garage. Adds MidiMate emulation. No actual MIDI in/out and just pipes basic MIDI events to the system MIDI player, but it's enough to get MidiTrack III to play.

- Devices: Added SX212 modem emulation.
- Fixed Autoselect not sticking for firmware mode.
- Firmware is now sorted internally so auto is more consistent.
- ATOS: Fixed keyboard repeat timer and character escaping compatibility issues.
- Added SX212 emulation support. Additions disk now contains an SX212 handler.

Altirra v2.60 test 35 [19.01.2014]
- XEP80: Set horizontal/vertical position commands now update the cursor address.
The horizontal/vertical position commands were updating the cursor position but not the cursor address. This version should fix it.
Altirra v2.60 test 34 [18.01.2014]
- Debugger: Added .diskreadsec and .diskwritesec commands.
- Debugger: Added dbi (dump bytes with INTERNAL text) command.
- Simulation: Added support for more realistic power-on memory patterns.
- ATBasic: PTABW is now supported.
- AltirraOS: Cassette boot now reads EOF record.
- AltirraOS: Fixed diagnostic cartridge handling.
- Cassette: Fixed inconsistent motor control state when using C: patch with short IRG mode.
- Debugger: Debug display now reflects CHACTL bits.
- GTIA: Fixed DMA reads from hardware registers.
- XEP80: Move Cursor to Start of Logical Line ($DB) no longer moves cursor to left margin.
- Added support for 512K 5200 cartridge. (Bryan, do you have a name for this?)
- Debug display now uses CHACTL
- Fixed XEP80 "Move to logical line start command" -- DOS CP now works
- Fixed diagnostic cartridge support in ATOS
- Fixed ANTIC reads from GTIA registers
- Fixes for cassette boot bugs exposed by XEX2CAS (ATOS wasn't reading EOF record, and C: acceleration was shutting motor off without updating PIA).
- ATBasic updated to 1.35 -- added PTABW support and fixed crash when DOS command fails. Did you know that JMP (DOSVEC) can return on a MEM.SAV error?
- Added support for more realistic DRAM power-on patterns. This affects software that fails to properly initialize high RAM under the OS or extended RAM. This supercedes the old randomize memory debugging option and is now under System > Memory Config > Power-on Pattern. The three patterns implemented are from my 800XL, 130XE, and 800XL + U1MB.
- Lots of changes to the DOS on the Additions disk, but I don't recommend using this just yet.

Altirra v2.60 test 33 [08.01.2014]
- Problem with new burst I/O code. Also adds PAL-60/NTSC-50 support, a tweaked luma ramp based on hardware measurements, and reverts the gamma correction setting default back to 1.0. I tried to find a way to auto-compensate brightness for scan line mode, but couldn't find a satisfactory algorithm. Oh well, it's tweakable. I changed the registry path for the gamma correction value so it'll universally reset to 1.0 once even if it's been set manually, since previous builds would have auto-set it; you can change it back again if desired.
- Simulation: Added support for mixed NTSC/PAL ANTIC+GTIA combinations (PAL-60 and NTSC-50)

Altirra v2.60 test 32 [05.01.2014]
- Fixes and updates to filesystem routines. DOS 2.5 ED and MyDOS formats are now supported for read/write access and directory creation is now supported on MyDOS and SDFS disks. The file viewer now attempts to use Unicode to display some control symbols (works better on Vista+ due to better font support).
- Disk Explorer: Added read/write support for MyDOS and DOS 2.5 disks.
- Disk Explorer: Added create directory (new folder) option for MyDOS and SDFS disks.

Altirra v2.60 test 31 [31.12.2014]
- Problem: The 64 bit version of Altirra wont run on Win XP 64 Bit Pro, it gives a message "not a valid 32 bit application". Most other 64Bit Programs will run on the same Xp 64 Bit, But som other programs have had the same error. On Win 8.1 the 64 bit version of Altirra Runs, The Pc with XP 64 bit i use for older games, Emulators etc...
- Answer: XP64 for old games? The mutt halfway between XP and Windows Server 2003 that has terrible driver support and still can't run 16-bit applications? Seriously? Why aren't you running XP32? The "not a valid 32 bit application" happens when the application is built for Vista or above.
Altirra v2.60 test 30 [31.12.2014]
- AltirraOS: Fix timeout for SIO operations.
- AltirraOS: Fix ESC-Clear handling in E:.
- ANTIC: Improved emulation of phantom P/M DMA effects
- 1030 ModemLink bootstrap is now supported. Required firmware image is $2880 (10368) bytes, consisting of the 128 byte boot sector with the $2800 ModemLink and T: handler software afterward.
- Added workarounds so SDX PRN: can run in intercepted mode (no line limit).
- Emulated CIO devices hook properly with OS-B again.
- Phantom player only DMA effects are now emulated (DMACTL=$26, GRACTL=$07).
- Fixed 850 firmware hotloading.
- Fixed incorrect initial translation mode for R:.
- Fixed some bugs in built-in OS (short SIO timeout, Esc+Clear not printing).
- Command-line images now set the default for the boot/open dialog.
- Fixed a bug in Altirra BASIC's BGET and BPUT commands (1.34 attached).
The 1030 boot sector initializes the T: handler before returning to the OS, so yeah, the type 3 poll is too late. Need a redump from just the SIO read, without the boot. No rush, though -- thanks for the dump work so far. As far as I know, the 1030 doesn't use the motor line but still uses the command line for control, so I'm not sure why using a cassette drive with it is inadvisable.
