This is a modified version of MAME with modifications in Psikyo SH-2 emulation (tgm2, tgm2p) that eliminate one extra frame of lag compared to vanilla MAME. It also includes the TGM enhancements listed below, but no inpview. Because this version is based on MAME 0.137, it also fixes graphical bugs in tgm2p, most notable of which being the blue boot-up screen.
This is a modified version of MAME with some modifications aimed to enhance the TGM experience and WolfMAME's inpview modifications.
Installing
After you download a version that fits your OS, use it like normal MAME
If you have MAME installed, you can put it there
Differences from original MAME
Only runs tgmj, tgm2 and tgm2p
These games are configured to 4-way stick, which makes MAME favor the last pressed direction For instance, [left; left+down; down] will send down to the game on the second input sequence
Polls input much more frequently and before executing the emulated CPU time slices (this is a brute force modification) TODO: poll input when the emulated machine polls input (this is the ideal modification)
Pressing opposite directions favors the most recently pressed one, and only locks if both become pressed simultaneously Exception: if up+down become pressed simultaneously, it favors up
Notes
The only difference between mametgm.exe and vmametgm.exe is that the former is compiled using GCC and the latter using Visual C++ 2005 Most people report that the Visual C++ version is faster
The Linux and Mac OS X versions are based on SDLMAME
It maked tgmj less playable due to the introduced processing overhead, but tgm2 and tgm2p are fine
It produces/reads .inp files incompatible with the original MAME
