MasterGear vs Retropa

MasterGear emulates 8-bit SEGA consoles and computers, including MasterSystem, GameGear, SG1000, SC3000, SF7000, Mark2, and Mark3. It runs on Windows, Linux, and Android. The maker says hobbyists can use it to debug software without rare development hardware. Documentation reports support for about 98% of the maker’s SMS, GG, SF7000, SC3000, and SG1000 cartridge and disk images, while noting compatibility is not complete. Emulated hardware includes the Z80 CPU, console video processors, SN76489 sound, and Mark3 YM2413 FM sound. It can save and load emulation states, but state files are not guaranteed to work across versions on different hardware. Other listed features include automatic GZIP ROM handling, MIDI soundtrack logging, a built-in debugger, cheat support, and NetPlay. Windows and Linux are free; the Android plan costs 430.00 USD once. Game ROM images are not included, and source code is not publicly available.

Retropa is an emulator for handheld and arcade games on iPhone and iPad, with Mac listed among its supported platforms. It covers 14 handheld and console systems plus arcade families; listed systems include GBA, Nintendo DS, NES, Super NES, Genesis, WonderSwan, Neo Geo Pocket, and Master System. The free plan costs nothing and includes handheld and console systems, imports, controller templates, Delta skin import, save states, and rewind.

Compatible external controllers and ready-made templates are supported. Retropa Plus adds arcade families, premium skins, console mode, advanced save workflows, adaptive touch controls with five styles, and 64 listed display filters. Saves can be backed up and restored with iCloud Drive. Game files stay on the device, and no account is needed to play. iPhone and iPad require iOS 18 or later.
