MESS v0.147u4 is released. MESS is an open source project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.

[Team Europe, Curt Coder] -pico.xml: new Japanese dumps added [Team Europe] -added software list for NEC APC [kaylee] -added PCB readme for FM Towns Marty [Guru] -xerox820: Added floppy software list. [Curt Coder] -xerox820ii: Added floppy software list. [Curt Coder] -pico.xml: added a new Euro dump and better documented some of the older dumps. [TeamEurope] -comx35: Added floppy software list. [Curt Coder] -ibm5150.xml: added some redumps and new dumps. [Kaylee] -wangpc.xml: added some new dumps from Don Maslin's archive. [Kaylee] -Add another CP/M8-6 version to the ibm5150 software list [Kaylee] -trs80m2: Added floppies to software list. [Don Maslin's archive] System Driver Changes: ---------------------- -Sega VMU added more bioses [El Barto] -qx10: Downgrade floppies to DD [O. Galibert] -super6: Added original BIOS. [Al Kossow] -APC: Fixed a few missing keys (a few are still missing though), and hooked the rtc clock, command and strobe lines up in a plausible configuration. The status line clock now works though shows an invalid value for year (the upd1990a didn't have a year response, so perhaps whatever rtc is being used here is a later variant which does store a year). The "date set" command doesn't work properly and doesn't even seem to poke the rtc at all. Needs further investigation. [Lord Nightmare] -z800x: Fixed some incorrect opcodes and address register math in segment mode. Olivetti M20 now can boot PCOS to the prompt. [Christian Grössler] -Minor fix to the character tile row ordering in apc [Lord Nightmare] -esq5505 updates [Christian Brunschen, R. Belmont] * Fixed up clocks for 21 vs. 32-voice models * Added ROMs for the 12-bit sample region on the SD-1 and SD-1 32-voice * Minor cleanups -Fixed upd765 SIS status when fid = 4, this makes NEC PC-88VA to attempt to DMA from floppy. [Angelo Salese] -bw2: Fix disk select and quick hack to make the timings work [O. Galibert] -Olivetti M20: improved keyboard and floppy handling [Christian Grössler] -fixed various bugs with Acorn Archimedes IRQs [Angelo Salese] -mirage: Make it boot by whatever means necessary [O. Galibert] -Finished sample ROM dump for SD-1 & SD-1 32 [Christian Brunschen] -Mirage: lots of documentation from the schematics, added preliminary LED hookup [R. Belmont] -a7000: Added RiscOS roms 3.60, 3.71, 4.02 and 4.39 [robcfg] -mu100: Main screen turn on! [O. Galibert] -pc98: Add its specific almost raw fdi disk format [O. Galibert] -macrtc: Remove weird address swizzle that confused systems with extended PRAM [Rob Braun] -studio2: Documentation update. [Stiletto, Guru] -mu100: Added older BIOS ver 1.05 [Stefan Lindberg] -Implemented proper IRE and phase value to the palette for Atari 7800 [Robert Tuccitto] -Mac: added "image" card which allows direct read/write access to any vMac/BasiliskII compatible image under 256 MB, including HD floppies. Disk is bootable if set in the control panel but only can eject from Finder. [Rob Braun, R. Belmont] -nubus_image: revised firmware allows multiple cards to work [Rob Braun] -nubus_image: add eject/insert support [Rob Braun] -sf7000: Fixed floppy. [Curt Coder] -m20: Implement memory map correctly. BASIC now shows its startup banner. [Christian Grössler] -vt100: added redumps of some of the vt102/vt131 roms [pjustice] -vt100: updated a bunch of driver notes and rom defs to reflect current research [Lord Nightmare] -sf7000: Verified floppy format gap sizes. [Curt Coder] -vt100: Verified that the checksum of the typed-from-manual 23-018e2 character generator ROM matches the dump from the actual chip. [Lou Ernst Jr.] -sms.c: Improved support for '3-D' games. [Enik Land] -dc: Added European DC bios 1.01c [BadAd84] -mackbd: dumped correct ROM, prep for actual emulation [Lord Nightmare, R. Belmont] -a7800.c: Adjusted colorburst/tint/hue of entire palette to closer reflect default hardware configuration setting of ~180 degrees [i.e. $17 = 179.92706396 & $18 = 179.927063726]. [Robert Tuccitto] Source Changes -------------- -Added proper char roms for Wyse700 [John Elliott] -upd765: Handle the rate correctly in FM [O. Galibert] -upd765: Don't choke on DDAMs [O. Galibert] -upd765: Reset MA when sector is found on write data too [O. Galibert] -imd: Accept versions with single-digit minor [O. Galibert] -upd765: Get ready from the correct place in sense interrupt status [O. Galibert] -upd765: Better integration and support of FM [O. Galibert] -pc floppies: Merge the common parts of d88/imd [O. Galibert] -floppy: Fix index pulse generation when motor is always on [O. Galibert] -floppy: Added macros for declaring modern floppy formats. The generic floppy formats (D88/DFI/IMD/IPF/MFI/MFM) are now automatically supported in each driver using the modern floppy code. [Curt Coder] -wd1772: Improved interrupts, added ready handling and FD1793 variant. [Curt Coder] -floppy: Default on head 0, not 1 [O. Galibert] -upd1771.c - additional comment updates, including some upd1771 patents and internal workings information. [Lord Nightmare] -wd1772: Added FD1771 and FD1797 variants. [Curt Coder] -upd765, wd1772: Move to emu [O. Galibert] -wd1772: Rename to wd_fdc [O. Galibert] -upd765: Externalize the fdc [O. Galibert] -wd_fdc: Add comments on the family [O.

Galibert] -wd_fdc: fm support, need to review all timings [O. Galibert] -floppy: Enhance ready support [O. Galibert] -wd_fdc: Interrupt on ready support [O. Galibert] -upd765.c: changes to busy flag, r/w sector increment and reset int [Carl] -upd765: Try another hypothesis [O. Galibert] -floppy: restore/recalibrate is supposed to work like this [O.
