Menu Shader Pipeline bug is present still..
Under Settings >>. UI then Appearance Settings (xmb menu)
Edit: have not verified but those settings may only appear in XMB view. because its a UI setting for XMB;s background.
Edit 2: Online Updater (obviously wont work ), but when selecting it, there is a text overlay bug.)
Edit 3: Thumbnail downloader - no way to download thumbnails currently (expected if not using official redepository)
Edit 4: CollecoVision issue w/ bluemsx core:
So this a simple core issue, not just a PS3 one but when you have colleco roms and they are scanned and a playlist is created there is a bit of an issue. You can not directly launch those roms if you try it will freeze. The reason why with this core to change system it can emulate is via the "Core Options" when you enter the Quick menu in game. So the dumb way to launch a Collecovision rom is in this fashion.. You must load a MSX rom to start, that way soon as game boots up you have access to the Quick menu and then you can enter in to the core options and then change the "emulated system" to colleco and then you can then load a colleco rom. THIS IS A SERIOUS CANDIDATE TO MAKE Colleco emulation on this core a standalone core with colleco values locked..
if you scan collecoVision roms into the playlist. While bluemsx play them. You cant boot them directly. It will freeze the console. because you have to set the emulated systems in that core via the core options. So bluemsx only emulates when you load the core and then goto core settings and collecovision and then boot a rom will it work.. This needs to be created into a a single core for collecovision
Edit 5:
mGBA is this working for anyone, Bios is optional but i could not get it to work
VBAnext worked,. Mario Kart Super Circuit (rom tested).. Resulted in black screen console freeze.
