First is MAME4ALL v1.3, which has a host of new features. You really do need to read the "whatsnew.txt" file included in the Binary download for all details. The "readme.txt" is also updated so please look at that for updated information on controls.
Quick summary of the major news:
* Vastly improved front-end, now featuring full snapshot preview support. Almost 2000 snapshots are included, all taken from within this version of MAME4ALL!
* Huge number of bug fixes, including a long standing sound bug which improves sound for many, many games! Including the newly supported Zwackery.
* Huge number of new games added and existing games updated.
Zwackery now works, nice game and despite needing 6 buttons, plays fine once controls are customised.
Macross, new game added, complete with sound.
Konek-Gorbunok, another new game added.
GCW-Zero version of MAME 0.37b16, MAME 0.66 and MAME 0.84 coming soon, complete with integrated frontend and preview snapshot support.
