Crucible V2.0-beta Released! (Nov 14, 2024)
Explore the latest beta version of Crucible, the ultimate ROM programming app for vintage Mac enthusiasts.
New Features in V2.0-beta:
Flexible ROM File Creation
Create ROM files in single, 2-split, or 4-split modes, accommodating different configurations like Lo/Hi or LL/ML/MH/HH. Split modes cater to general Mac ROM chip configurations, not just ROM SIMMs.- Why is x2 necessary? This is because it is often effective to flash twice in order to make an EPROM with double the capacity work properly. For example, when flashing data from a 27C256 to a 27C512.

Join Mode
Seamlessly combine ROMs, like merging a BootROM with a BaseROM.
