Hi,
Something that has bugged me for a long time when playing TGM2+ on a CRT: While you play single player, the "INSERT COIN" message on the player 2 playfield keeps blinking. Every time it appears, the extra bright area makes the tube draw more beam current, the high voltage sags slightly and the picture "breathes" (blooming). The result is a small, constant horizontal wobble of the left edge of the screen, near the bottom of the player 1 playfield.
At 20G, with your eyes locked on the stack, these tiny lateral movements are really distracting and super annoying. Once you notice it, you can't unsee it. (OCD kicks in really badly
)
@Darksoft has been kind enough to modify the program ROMs U21 and U22 to remove the "INSERT COIN" message from the P2 playfield. Nothing else is changed: the graphics ROMs are untouched and the game plays exactly the same. The P1 playfield stays perfectly still now, no more blooming every second.
Details:
Game: Tetris The Absolute: The Grand Master 2 Plus (Psikyo SH-2) (ROM: tgm2p)
Modified files: program ROMs only (U21 / U22)
Tested on: original PCB and MAME
Distribution: IPS patches to apply to your own dump. Install on original hardware
Apply the patches, burn both files on 27C4096 EPROMs and replace the two program ROMs.
All credit goes to @Darksoft for the hack.
Feedback welcome, especially if you spot any side effect.
We must be 3 people or less caring about this in the whole universe, so not expecting too much attention... But if you do, don't forget to send a thank you to the one that made this possible.
