This past weekend ZX-81 released an update to his popular MSX emulator. For those who haven’t heard, bird isn’t the word — PSPMSX is. Most notably PSPMSX version 1.4.0 incorporates a cheating and memory monitoring engine; similar to weltall’s CWCHEAT for PSP/PSOne titles.

PSPMSX is ported from Marat Fayzullin and Vincent van Dam’s work; it emulates the MSX, MSX2, and MSX2+ 8bit home computers.

PSPMSX v1.4.0 changes:

• Cheat support!
• Memory monitoring engine to find your own cheat code
• Zip rom files are now decompressed in memory (much faster)
• New render modes (x1.25, x1.5 and x1.75)
• Add vertical shift & vsync feature
• Improve file requester with virtual keyboard to choose sequentially rom files beginning with a given letter
• Add documentation for settings in help menu
• The virtual keyboard is now usable in the file requester menu to choose the first letter of the game you search
• In the emulator menu you can go directly to keyboard and settings menu using the L-Trigger key.
• Source code can now be compiled to build a linux version
