MasterGear vs SMS Plus GX

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.

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.
