Jeszcze jedna odsłona Altirry z dość znaczną ilością poprawek, m.in. niezbyt urocze wykrywanie wyciągniętego cartu (abris) i wreszcie Phaeron ograniczył wielkość wyświetlanego obszaru (koniec śmieci, po bokach ekranu, których nie powinniśmy nigdy widzieć) - (View -> Overscan Mode -> OS Screen Only), jednak tutaj uwaga, bo np. przy włączonym trybie overscanu większość loaderów w trybie gr. 0 (tekstowym, jeśli dobrze pamięta) jest niewidoczna - szykuje się więc jeszcze jedna poprawka;P Oczywiście powyższe zmiany nie zamykają listy wygładzeń w tej wersji.
![[ATARI] Altirra 2.0 test XXI](www/picphoto/19a443df1.jpg)
Version 2.00 test 21:
- bugs fixed
- HLE: Screen setup now matches the display list and playfield addressing of the stock OS ROM.
- HLE: Fixed cartridge handling so that cartridges are run after disk boot completes.
- HLE: Added known RTS instruction at $E4C0.
- HLE: CIO now allows SPECIAL commands to be issued on a closed IOCB.
- HLE: Screen setup now matches the display list and playfield addressing of the stock OS ROM.
It also contains a fix for not being able to format double-sided disks, which I didn't add into the changelog because there was already an entry for fixing PERCOM block problems.
Version 2.00 test 20:
- features added
- Disk: Disk explorer now properly increments volume sequence number when modifying SpartaDOS X images.
- Disk: Live disk images can now be explored directly from the disk drive entry rather than requiring an unmount and remount.
- Disk: Disk explorer shows timestamps.
- Disk: .ARC compressed archives can now be explored.

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.
