PlayStation Portable homebrew developer Zx-81 has once again updated his port of MSX emulator for the Sony PSP, PSPMSX, bumping it up to version 1.2.4. This release has a number of additional features and bug fixes.

PSPMSX is a port of the MSX emulator originally made for Windows and Unix, fMSX, and it emulates the MSX/MSX2/MSX2+ home computers. For version 1.2.4, Zx-81 added an autofire mode, plus quick save/load and settings hotkeys. Here's the full changelog from Zx-81's official site:

• Add missing keys such as HOME, GRAPH, STOP (Thanks to symBioT for the bug report)
• Auto joystick fire mode, press RTrigger+X to switch it on/off (useful for games such as 1942)
• Add several new hotkeys :
• settings such as fps, render mode, auto fire speed can now be directly modified inside the emulator (no need to enter in the settings menu)
• quick save / quick load current state (no need to enter in the main menu)
• Bug fix in the low battery watchdog
• Analog pad can be used in the rom file requester
• RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
