Altirra 2.5 Test 30 is released. Altirra is an Atari 8 bit Emulator on the Windows/DOS platform. Altirra emulates several models of the 8-bit Atari computers. This includes the the 800, 800XL, and 130XE versions. Altirra is quite matured now, and IMO, the best Atari Emu currently! It also supports some copy protected games properly in emulation.Altirra 2.5 Test 30 Changelog:
| - Just adds The!Cart EEPROM support and some math pack changes in the internal OS (rounding on cancellation and faster multiply/divide), so I didn't bother posting it here. But hey, have at it.... I was looking at doing a 65C816 version of AltirraOS, but it looks not worthwhile at this point. The 65C816 has an absurd amount of interrupt overhead in native mode, and REP/SEP instructions make it hard to leverage native mode without bloating code. On top of that, it seems hard to optimize the math pack for '816 as the mantissa order of decimal floats is backwards from what would be needed for 16-bit arithmetic. Sigh. |
