Despite noting that the previous release was the "final" release of PSPMSX, homebrew developer Zx-81 today released another update to his popular MSX and MSX2 series emulator. Hey, we're not complaining!
Changes in this release include considerable speed improvements while using GU render modes, as well as various changes made to the core settings menu and default settings options.
