Since you need ISO 58 to use sega cd suppoort at full speed from USB...

Maybe have the app check if 58 is loaded, and if it isn't, then have it reload into 58? For whatever reason, getting this thing to boot with anything other than the homebrew channel is a big pain due to this.

Question, does MegaCD require ahbprot access to work right, because it works fine when booted through HBC, but does not when booting from other dol loaders.

be more precise, what does or not "work fine" exactly ?
ahbprot is only needed for dvd access

It runs CD games slower from USB, presumably due to a lack of 2.0 speed. I assume it's a IOS 58 thing. I'm booting it with r1203 of USB loader GX's homebrew launcher (with GX being booted from a forwarder installed in priiloader mod) It seems random what it boots apps with, as of now. I think Cyan is gonna add a force homebrew loading with ios 58 setting, so i wouldn't worry too much. Was just wondering, since Genplus GX has always been stubborn with what it's booted with.

The game that runs all slow is sonic cd, btw, both J and U versions.

Any games will run slow from a slow USB device, if it only affect a specific game then this is no normal, unless that's the only game you tried which had cd audio or is accessing the disc continuously during gameplay. Sonic CD is notoriously slow on real hardware as well, compared to Sonic on Mega Drive, so there might be unnormally slow and normally slow games.

Finally, genplus gx does not care from where it is booted from, it's more that some loaders might be coded by people who don't really know what they are doing and have been copypasting dol loading codes from other old loaders without understanding how it works or what limitations were
It's up to the loader to setup correct IOS for homebrew, not homebrew itself, it's not "forcing", it's the way it should be done

The thing is, it works fine and is at full speed when the emulator is booted with homebrew channel. I'm not sure what the problem is, really. My best guess is that the emulator isn't being booted with IOS 58, for 2.0 speed access.

With apologies to Eke-Eke for speaking on his behalf, what he's saying is that the problem is external to Genesis Plus GX. It would be more productive to report this issue to the developers of the loader you're using to get them to fix it on their end.

@ vaguerant Of course its an external issue. I was simply proposing an internal solution. I knew that from the beginning. He made it WontFix (which, i honestly expected that) So, I just asked a question that would help me understand the nature of the problem, so that i could fix it, since he IS the coder of this fine emulator, i figured he could help me, and he did.

And thats been already done, btw. As I said, Cyan is working on it.
