This mod makes MAME poll for host input more often. It makes TGM even less playable (too heavy for my poor laptop), but it is not that heavy with TGM2 and TAP.
This is a modified version of MAME with some modifications aimed to enhance the TGM experience and WolfMAME's inpview modifications.


In addition, it handles pressing opposite directions in a different way:
'''Installing'''
* If you press left, then right without releasing left, it will read left then right
* After you download a version that fits your OS, use it like normal MAME
** Original MAME locks (i.e. ignores) both left and right if you pressed right without releasing left
* If you have MAME installed, you can put it there
* This also works for right->left, up->down and down->up
* Still, if you press left and right at the same time, it will lock both
* However, if you press up and down at the same time, it will prefer up


TGM and TGM2/TAP are also set to 4-way, because on the keyboard or on a 8-way stick, pressing left, left-down, down does not lock a piece on left-down but only on down (some may say this is a cheat, but I say it's an enhacement: you can't possibly press left-down on a 4-way stick, so when you press left, down it's really left, down, not left, left-down, down).
'''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<br />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)<br />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<br />Exception: if up+down become pressed simultaneously, it favors up


Note: this mod produces/reads .inp files incompatible with the original MAME.
'''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<br />Most people (including me) 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

MAME is an open source project, which give the chance to test code changes.

Input mod

Current version: 0.133

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 (including me) 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
  • Input Viewer from WolfMAME: try -inpview 1
