This patch modifies the Tetris: The Grand Master ZN-2 binary to allow it to run on regular retail PlayStation hardware.

All the ZN-2 board specific hardware accesses (ROM, EEPROM, 4MB RAM, JAMMA I/O, QSound, Country ROM) have been replaced or patched out.

The button mapping is configured to match the Namco Arcade Stick / Hori RAP2 layout.

In order to run this you will need to:
- extract the game binary and data from the ROMs (ate-05m.3h and ate-06m.4h), you can use the included extract_tgm.sh script for this
- patch the MAIN.BIN binary with the included IPS patch(es). The core patch (tgm_psx_v1.3.ips) is required, the others are optional
- follow the intructions in cdda_music.txt to create the music tracks
- compile bin2exe_tgm.c and convert the patched MAIN.BIN binary to a PSX-EXE ("./bin2exe_tgm MAIN.BIN MAIN.EXE")
- master a disc with the extracted ROM contents, the converted PSX-EXE, and the included SYSTEM.CNF file ("mkpsxiso TGM_PSX_CDDA.xml")


v1.3 changes:
- Added background preloading to allow background graphics to change while CD-DA music is playing
- Adjusted the track positions for CD-DA music tracks, this should reduce the short silence at the start of some tracks
- Integrated the previously optional music playback code into the core patch (use an older version if for some reason you don't want the music)
- Added optional IPS patches to change the region to USA or EUR (which changes the attract mode text to English)
- Added button mapping for L2/R2 to 'down' for more comfortable playing on a regular PlayStation controller
