So here it is, tested on 2 different Macbooks with the same Mash-Mods.com SNES RETRO FLASH CART
. Works with HiROM and LoROM ROMs up to 4MB. Included is a Console that logs everything that happened after the functions has finished. It may seem like it has crashed, but it is working. It can take up to 5 minutes for the largest ROMs. I am working on a complete rewrite but that won't be for a while. Everything should be self explanatory, if not email me and I'll post replies here. Be sure to install the driver first.
