Patch to fix graphics corruption on MSX1.
Dig Dug (Namco) is a false Rom of 32kB. This patch allows to make a Rom in real size (16kB).
The original firmware searches if a ROM cartridge is inserted in the slot 1 or 2, if no ROM cartridge is found, the firmware is executed. Which is practical but the secondary slots are not taken into account, so if you insert a disk interface with several functions (memory expansion, megaflash-ROM, etc.), it will not be detected and the firmware will start, which causes a conflict.
These patches add Keyboard support, modify the gameplay with joystick and fix PSG I/O ports. In addition, depending on the patch you can change the file format.
When the patch is applied you can play with keyboard (cursor key and space key).
You can still play with a joystick but now using both buttons.
These IPS patches allow to convert the following 22 Roms to SCC sounds.
Patches are based on NandemoSCC by Tiny Yarou and enhanced by GDX.
