All right, I managed to connect my MP4 (as I don't know its model or anything, i'll refer to it as 9504, item number on DealExtreme).
Mine does have a different Sunplus firmware from the rest. It's got a blue background and well, it emulates GB/GBC and this strange game format I talked about before, .BIN, games on that format seem to be made by Sunplus and I only have found the 3 ones that came on my player's memory, you can download them from here: http://uploaded.to/?id=yn9jon&setlang=en
I'm now uploading the firmware and the disk A and B images for you to test them. Upload all the firmwares you have so we can test if they're compatible between players and if we can find any extra features.. Skinning is quite easy, just requires modifyng the .jpg's. I think there's no risk of bricking the device, as the FW download feature isn't dependant on the firmware itself (at least while pressing a key when plugging the USB port, only way for me).
Upload the diska and diskb images too, I think they're also needed (I downloaded the .bin firmware from the download section, but the screen showed gray and the unit hanged, maybe because of those images being not compatible).
BTW you may need to modify the USB device ID on the .inf file of the driver so it detects your device. When on this firmware mode it detects as a MMCatch Multimedia Device or something similar (not as a storage device).
Oh, and looking at the images, it seems there's a scientific calculator somehere on the firmware.. but I can only access a simple calculator..
NES and GB emulators are called, according to the hex editor, N1 and G1 respectively.
Edit: Here you have the firmware: http://zen.itram.es/files/PMP_DX_sku9504_blue_background.rar
