which some paths that were constructed from a template with variables would sometimes get an extra garbage character thrown in
2017-04-21Fairly major rework of how active/passive is handled along with how the V30 ↵Michael Pavone
mode bit is handled. Allows the vertical border extension trick in Overdrive 2 to work right
2017-04-21Minor optimization to avoid invalidating translated code when the bank has ↵Michael Pavone
not actually changed. Makes a nasty edge case in the 68K debugger slightly less severe when dealing with code that uses banking

2017-04-16Force display on in stateview if given a save state with the display offMichael Pavone
2017-04-15Fix copy pasta error in handling of Z80 VDP port reads. HV counter reads are ↵Michael Pavone

debug view
2017-04-04Allow a .l suffix to a memory print command to allow fetching and printing a ↵Michael Pavone
longword
2017-04-03Improved printing of word at absolute address to support reading from all ↵Michael Pavone
address types. Implemented support for printing the value pointed to by a register. Removed abuse of read_dma_value in internal debugger.
2017-03-31Allow adding .w or .b to select just the low word or byte of a register in a ↵Michael Pavone
68K debugger print command
2017-03-31Allow printing current frame number in 68K debuggerMichael Pavone

Fantastic Dizzy and Kid Chameleon
2017-03-29Added Might and Magic III prototype to ROM DB as it requires SRAM, but does ↵Michael Pavone
not indicate it in the standard header

(incorrect header) and to support some more unlicensed Chinese games with fixed value registers as documented by Andlabs on the Sega Retro wiki
2017-03-29Allow games to be specified in ROM DB via sha1 instead of product ID. Added ↵Michael Pavone
a new ROM DB memory map device type fixed for emulating simple fixed value copy protection registers. Used those two features to support Ya Se Chuan Shuo via a ROM DB entry.
2017-03-28Fix exit trace mode edge case. Call do_sync if trace mode bit is changed in ↵Michael Pavone
eori sr
2017-03-28Implemented M68K trace mode. Some edge cases/SR update paths still need workMichael Pavone
2017-03-27Add Japanese version of SSF2 to ROM databaseMichael Pavone
2017-03-27Initial implementation of YM2612 SSG-EG modeMichael Pavone
2017-03-25Basic implementation of CSM mode that should handle documented edge cases. ↵Michael Pavone
Dodesn't handle the weird undocumented edge cases I don't have a good understanding of yet though
2017-03-25Fix latching of V32 mode bitMichael Pavone
2017-03-25Prevent blowing past our native translated instruction size of 255 bytes ↵Michael Pavone
when translating movem with a large register list. Fixes bug in which Fantastic Dizzy was completely broken on 32-bit builds
2017-03-22Fix SBCD edge cases to pass Flamewing's test ROM. Could use some cleanup to ↵Michael Pavone
produce better code for the SBCD case, but produces correct results now

2017-03-21Make save directory configurable. Satisfies ticket:4Michael Pavone
2017-03-21Allow variables in screenshot_path like initial_pathMichael Pavone
2017-03-21Don't leak a ternary tree when building the menu's initial pathMichael Pavone
2017-03-21Allow initial_path to contain variable references which allows the default ↵Michael Pavone
value to be actually specified in the default config file
2017-03-19Adjust Z80 interrupt pulse duration to match hardware measurementsMichael Pavone
2017-03-19Change handling of invalid scroll plane sizes. Fixes title and high score ↵Michael Pavone
screens in The Incredible Hulk

Testing ROM
2017-03-19Minor fix to hacky refresh emulation code to more closely match my intentMichael Pavone
2017-03-19Add Mega Everdrive style header detection for homebrew using the SSF2 ↵Michael Pavone
mapper, though without the Mega Everdrive extensions. Properly invalidate translated code on a bank switch when using the SSF2/Sega mapper

sound after entering pause menu in Pacman 2: The New Adventures

negative
2017-03-17Fixed some deficiencies in the 68K test generatorMichael Pavone
