MESS 0.145u8 Released
Multi Emulator Super System. MESS is a source-available 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.


New System Drivers Supported:

Systems Promoted from GAME_NOT_WORKING:

Skeleton drivers:

System Driver Changes:
-gbcolor: fixed sprite regression. [Alegend45]

-kc: Added emulation of GIDE interface. [Sandro Ronco]

-Apple2: Preliminary infrastructure for emulating Apple IIe auxiliary
slot cards [R. Belmont]

-x68k: Added clone X68000 Super (with its own internal SCSI ROM dump).
Added internal SCSI ROM dump for the XVI. [Anna Wu, Barry Rodewald]

-apple2: Added "The Mill" 6809 card. BASIC demo program works; OS9
and Excel Flex appear to need undumped additional ROMs. [R. Belmont]

-pc: Corrected SN76496 clocks to /4 of sysclock instead of /5, fixes
pitch to match video [MooglyGuy, Kef Schecter]

-tvc: added cartridge support. [Sandro Ronco]

-c64: Added preliminary support for the IDE64 v4.1 cartridge.
Load/save from BASIC works, but there is graphics corruption in the
menu, and USB/CF is not supported yet. [Curt Coder]

-vectrex: support 64k bankswitched carts and carts with SRAM
[mkasick, kbare]

-IBM PC drivers: Implemented the PC keyboard connector as a slot
device. In the future this will allow the user to select which
keybaord to use with an emulated PC. Converted the Keytronic PC3270
keyboard implementation to C++ as an example pc keyboard.
[Wilbert Pol]

-osborne1: Added IEEE-488 bus. [Curt Coder]

-PC Drivers: Updated remaining PC/XT and AT drivers to use the
keyboard slot implementation. Removed legacy device implementation for
the Keytronic keyboard. Removed an unneeded include from
drivers/amstr_pc.c. [Wilbert Pol]

-DEC Rainbow: fleshed out the Z80 side including partial WD1793 hookup
and correct shared RAM handling, but system doesn't get any further
yet. [R. Belmont]

-DEC Rainbow: initial Z80/8088 comms work, ends with Error 10 now instead
of 18 [R. Belmont]

-DEC Rainbow: Hooked up VBL and Z80->8088 IRQs. Still doesn't boot,
but closer than ever. [R. Belmont]

-DEC Rainbow: 82/83 to the diagnostic port is meant to reboot the Z80.
This passes the "memory arbitration test". [R. Belmont]

-DEC Rainbow: Improved Z80 control, fixed weird garbage on screen and
eliminated "Z80 response" system error. [R. Belmont]

-DEC Rainbow: Hooked up keyboard i8251, but our 8251 core needs
interrupts. [R. Belmont]

Software Lists:
-snes.xml: verified more carts [MESSfan]
-pico.xml: new dumps added [Team Europe]
-apple1.xml: added a few more tapes [Anon01]
-tvc: added cartridges softlist. [Sandro Ronco]
-snes.xml: finished documenting unreleased titles, very special thanks
to Evan of snes central who made this a piece of cake [MESSfan]

Source Changes:
-ap2_dsk: added some missing defines and comments and a way to select
whether to use lenient (if the address mark contents are sane
regardless of whether the checksum byte was good or not) or normal
(only if checksum was valid) usage of the address marks. Also switched
the default output sector order from prodos order to dos3.3 order,
which is slightly more useful. Added a define to switch between the
three possible sector orderings: prodos, dos3.3, and logical.
[Lord Nightmare]

-dfi_dsk.c: fixed a nasty bug when reading df bytes with 0x80 set
throwing the timing way off; this makes most disk images decode a
whole heck of a lot better. ap2_dsk.c: fixed a nasty
array-out-of-bounds access problem if an address mark with an insane
sector value in it is read. [Lord Nightmare, Phil Pemberton]

-Fixed a logic bug in the dfi header check which surprisingly doesn't
come up at all on GCC (compiler bug?) but does happen on clang. Also
disabled some accidentally enabled debug code, and handle the case of
no index transitions at all properly. [Lord Nightmare, Balrog]

-Fix bug found by Clang (behavior *appears* correct but can't verify)
[Balrog, R. Belmont]

-3c505 improvements. Netbooting a MESS Apollo instance off a second
MESS Apollo instance is now possible, and Domain/OS 10.4 works.
[Hans Ostermeyer]

-Various Clang warning cleanups (and a few actual bugfixes) [Balrog]

-i386: Big pmode update. OS/2 2.1 more or less runs now. [Carl]

-ap2_dsk.c: Preliminary, working RWTS18 decoding support; Decodes disks
and shows ascii text; not sure if sectors are in the correct order
yet. [Lord Nightmare, Balrog, Roland Gustafsson]
