Tetris: The Grand Master ZN-2 to PSX conversion

Hack of Tetris: The Grand Master

Description:

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

ROM / ISO Information:

  • 78c2b1965957ff1756c25b76e549f11fc0001153 ate-05m.3h
  • c9262e8de14c4a9489f7050316012913c1caf0ff ate-06m.4h

This is so cool!

Reviewed By: BulkSlash on 18 Jan 2021

I knew ZN-2 was based on PS1 hardware but I had no idea games could be ported over. Given how eye wateringly expensive the JAMMA board is for this game, it’s great to have a way to play it on what is essentially “real” hardware. Definitely recommended!
