Kolejna testowa wersja Altirry, świetnego emulatora maszynek ATARI (XE/XL/7800/2600), autorstwa Phareona, m.in. twórcy VirtualDub'a. Wszystkich zainteresowanych kolejnymi betami, odsyłam do wątku na oficjalnej podstronie VirtualDuba poświęconej Altirry... Brrr... dość dziwny sposób obwieszczaniu światu kolejnych wersji testowych w komentarzach:).

- This version also supports intSDX 128 banking, so you can grab screenshots without working around the $D5xx banking issue
Alitirra 1.8 test 09
- I found the bug in 5200 Galaxian's controller calibration routine and added a workaround. The bug causes the game to split even/odd inputs instead of controller 1/2 as intended, but it typically works due to controller noise. I also fixed a regression in video recording with turbo.
Alitirra 1.8 test 08
- This version updates the input system to support relative/absolute positioning for analog axes and toggle/autofire modes for buttons. It also supports shift buttons so you can pack more functions on your controller than you have buttons. The Presets button has a sample mapping for the Xbox 360 controller that packs joystick port 1/2 and absolute/relative paddles onto one controller -- the left stick button switches between port 1/2 or absolute/relative and the right stick button switches joystick/paddle. You can do the same thing on any other mappings by binding buttons to an Input State controller to toggle flags and then selecting those flags under Condition for other controller entries.
I was struck by both nostalgia and ambition and started to write a new 8-bit Atari emulator from scratch. This is the result.
At this point, I've learned a lot more about the Atari and Altirra now emulates more than I ever had or did years ago, but I still work on it periodically. It also serves as a modularity test for the VirtualDub code base, from which Altirra shares some components. If you are struck by nostalgia too or have a desire to do some Atari development, perhaps it might be useful to you, too.
