Review zorrom algorithms #3

Open caps0ff opened 4 years ago

caps0ff commented 4 years ago

Summary: zorrom is a utility to convert mask ROMs into binaries. It would be ideal to port some old scripts into this framework to have a more uniform toolchain

Algorithms are typically implemented as a function that, given an address and offset, should return the row and column in the physical layout.

Example contribution: import sharp SM4 (ex: Nintendo 6102 CIC). We have binaries and images that were converted using a special script (may or may not have this). Compare the two and create an algorithm.

Here is an existing algorithm (Fujitsu DSP used in TGPs): https://github.com/SiliconAnalysis/zorrom/blob/master/zorrom/mb8623x.py
