Slot 2 Mapping Mapped Code
The v1 Asterix ROM corrects several issues in the v0 ROM:
- During the ending sequence, the v1 ROM loads a set of tiles into VRAM at address $0080 rather than $0000. This protects two required tiles from being overwritten, preventing corruption of the Getafix sprite. Accordingly, the sprite's tile indices are also changed.
|Getafix [v0]||Getafix [v1]|
- After the credits have shown, the v0 ROM leaves a flag set in RAM. This causes the ending sequence to show incorrectly if the game is completed a second time. v1 zeroes an additional byte of RAM, clearing the flag.
- The French text on the round VIII title card is corrected - in v0 the text is a duplicate of that used for round VII.
|Round VIII Title Card [v0]||Round VIII Title Card [v1]|
- Some of the French text in the attract sequence and on the round III title card is corrected:
These are the only differences between the v0 and v1 ROMs.
