Tecmo
From MAMEDEV Wiki
- Vgoal soccer - protection, H8 mcu, can detect if ROM has been changed, if so writes ROM ERROR directly to video ram, and refuses to do anything. Chris Hardy is working on this, attempting to run code from RAM with a fluke, we'll see what happens
- Tecmo World Cup 94 - same as above
- Deroon Dero Dero - aka Tecmo Stackers, looks like a really nice puzzle game, but has MCU protection. It hasn't been deteremined if this prevents ROM modification like Vgoal. Tests need to be run on PCB.
- Touki Denshou -Angel Eyes- - same board as above, protection might be different tho, we don't have this game PCB.
