Deweloperska wersja emulatora małego Atari [sdl] z poprawkami p. Tomasza 'krOtki' Krasuskiego, który walczy w dalszym ciągu z emulacją odczytu informacji z wirtualnego magnetofonu - nowa zmiana powinna ułatwić odczyt niestandardowych obrazów taśm. Po przetestowaniu paru archiwów widzę, że jeszcze dużo czasu upłynie nim wszystkie formaty będą dobrze obsługiwane - chociaż emulator nie jest on tak rozbudowany i zaawansowany jak Altirra, warto go śledzić, jeśli starczy cierpliwości p. Krasuskiemu, przynajmniej z odczytem kaset będzie mu dorównywać jeśli nawet nie przewyższać.
Barbarian - był jednym z tych programów legend, które człowiek nie mógł znaleźć, pomimo, że gazety pisały iż istnieje wersją na ATARI (a nie istniała). Dopiero polska firma LK AVALON na fali popularności tego tytułu stworzyła wersję na ATARI.

- Improve cassette emulation, to allow loading some non-standard tapes (e.g. Feud/Turbo 2600, Miecze Valdgira II, Operation Blood). Emulation of SERIN was inaccurate - new byte appeared in SERIN only if the serial input IRQ was enabled, and it happened 2 scanlines after the byte's transmission has _started_. On a real machine, a byte appears in SERIN at the same time the serial input IRQ is generated, that is, when the byte's transmission _ends_; and it happens even when the IRQ is disabled. The bug caused issues with tapes of _certain_ baudrates (e.g. 577 baud). Changed the way cassette IRQ is invoked - there is no notion of "cassette IRQ delay" anymore. Instead, CASSETTE_AddScanLine returns TRUE on SERIN update. Added partial emulation of SKCTL reset bits - due to improved SERIN accuracy proper emulation of serial IO resetting is now needed to load tapes correctly.

- Fixed a segfault when reading tape blocks longer than4096 bytes, by dynamically allocationg memory when needed. Blocks loadedwith SIO patch are now copied to Atari memory even when they are too short or the checksum is wrong - this duplicates the behaviour of the unpatchedsystem. CASSETTE_buffer no longer used outside cassette.c, so it's made static.

- Fixed a bug with PIA's tape motor state and COMMAND line state not being restored on loading of a savestate.
- Display SIO activity for tapes only when a tape image is attached.

- Added support for switching bettween tape loading/saving without need to re-attach a tape image. Added a "Tape management" menu with new options for tape rewinding and creating a blank CAS image. Added loading/saving of the currently attached tape image in the config file. Without the SIO patch, a user now must manually switch tape recording on/off if needed. Fixed some bugs and cleaned the code a bit.

Atari800 is the emulator of Atari 8-bit computer systems and 5200 game console for Unix, Linux, Amiga, MS-DOS, Atari TT/Falcon, MS-Windows, MS WinCE, Sega Dreamcast, Android and other systems supported by the SDL library. Our main objective is to create a freely distributable portable emulator (i.e. with source code available). It can be configured to run in the following ways :
