This Swiss team just posted another release, focusing on specific game enhancements and adding the ability to launch the Game Boy Player startup disc from an SD card. Of course, no one with SD launch access would want to use the GBP disc over the Game Boy Interface software, however being able to launch GBP from SD has always been a thorn in people’s side who wanted to test the original functionality.
More from the Swiss team:
“This release adds some more game specific video patches, improvements to IGR compatibility, the ability to invert the camera stick in games, and fixes support for the Game Boy Player Start-up disc from devices such as the SD Gecko. It also adds some on-screen descriptions/help to some of the settings available (prompted to press Y if available).“
