Debug apparatus and method for debugging game program in ROM cartridge
In a developing environment, a game program exists in a product ROM and a debug program exists in another ROM which is a test ROM. The debug program includes a time adjusting program and cther debug routine programs. The game program includes some statements for the debug program. When a ROM cartridge is produced as a product ROM cartridge, the test ROM is detached from the ROM cartridge and the statements for the debug program are deleted from the game program in the product ROM. The deleted area in the product ROM is left as an unusable area. However, the deleted area is very few, because the size of the statements for debug program is much fewer than the size of the debug program. Therefore, the game program is able to use almost all product ROM area. <IMAGE>
