While I wasn’t looking, the Atari800 emulator was updated to version 2.1 (current PSP version is at 2.0.3). Here’s what’s new (and not everything may be relevant to the PSP release):
New features
- added Axlon and Mosaic RAM expansions for Atari 400/800
- added emulation of 1400XL, 1450XLD, MIO and Black Box
- added support of .PRO copy-protected disk images
- implemented tape loading with variable bitrates
- implemented cassette writing via hardware registers
- added switching between NTSC and PAL color palettes
- added emulation of XEP80 and a prototype 80 column card for the Atari 1090 (SDL only currently)
- added emulation of CX85 numeric keyboard (Java and SDL only)
- NTSC Filter option added to UI
- monitor supports arrow keys – e.g. up-arrow for history
- R: device can be serial-only, network-only or both (selectable)
- R: device now supported on MS Windows and Dreamcast as well
- Falcon/TT: removed Devpac dependency in asm files (now gcc friendly)
Fixes
- fix for “Ilusia” demo
- better GTIA bug mode emulation
- POKEY sound: nonlinear mixing (not enabled by default), two-tone filter
- fixed POKEY registers: ALLPOT, IRQEN and STIMER
- various Atari5200 fixes
- fixed Atrax cartridge bank switching
- major source code cleanup, compiles with -pedantic etc.
- Save State: added support for Axlon and Mosaic (version increased to 5), fixed PBIM12 restoring, fixed PAGED_MEM error with POKEY, color palette restoring fixed
The lately-neglected PSP version should be updated within a few weeks.
Can You add a H: device and key for entering atari emulator menu in psp version?
H: device should not be a problem; however, the emulator menu is not likely to be added, because the PSP version has its own, and mixing the two menus together leads to information inconsistences that may lead to data loss (save state file de-synchronization, etc…).
This is true of all the emulators, not just this one, by the way.
