Breaker rozwi膮za艂 problem oficjalnej Alttiry Phaerona - jednak to jaknajsambardziej oficjalnie opublikowany plik.
Tak naprawd臋 Phaeron nie opublikowa艂 nowej wersji swojego emulatora ATARI XE/XL, nigdzie nie ma jego wzmianki na ten temat:) Zrobi艂 to za niego jeden ze 艣ledz膮cych w膮tek (breaker) - tak, czy siak mo偶emy pobra膰 now膮 Altirre, jednak w ostatecznym rachunku mo偶e si臋 jeszcze okaza膰, i偶 pojawi si臋 kolejne 1.8:)
Ze wzgl臋du na problemy pomi臋dzy emulacj臋 rozszerzenia VXBE (grafika) i ABXE (karta d藕wi臋kowa), nowa Altirra nie posiada tego dodatku, którym Phaeron zaj膮艂 si臋 par臋 bet wcze艣niej.

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.
