A big rounds of MiSTer core updates went out over the weekend. The most important is the addition of Ijor’s cycle-accurate Motorola 68000 soft-core to the Genesis core, as expected. As well as the addition of Sega Game Gear support added to the Sega Master System core, and official Famicom Disk System support added into the NES core.
Genesis:
– Cycle accurate CPU from ijor
– Tweaks for new CPU
– More workarounds for games using EEPROM, SRAM, J-CART
NES:
– Support for Famicom Disk System (You need to load original FDS BIOS before use FDS dumps!)
– More palettes
– Support for scaler coefficients (put them into Filters folder)
– Use T65 as a most complete 6502 CPU
– Many fixes
