You my friend are a genius - I updated the header and it totally worked.

Thank you so much for the quick response... I thought I was going crazy :)

It complains that the roms needs to run on an NTSC Genesis... but the region automatically gets set to JP regardless of the bios I use either at the root (boot.rom) or the cd_bios.rom that I place in the folder to override the default bios when I load the MSU-MD cart.rom.

I've checked the rom and ensured it is the correct CRC value before I patched. Is anybody else seeing this behavior? If so... have you had any luck resolving?
the fix has been pushed to the core not sure if its been released yet though
if you want a quick fix and have an io board load game so you get the error and then goto osd and change it to US then press the button labled user on the io it will reset without ejecting disk and reload and work fine

if no io you could hex edit the cart.rom to have EJU instead of JUE and it will work too
or wait for the fixed release
Interesting, this shouldn't be a problem as Art of Fighting on Sega Genesis USA has "U" in the header already, and the European version has "E". Is the region handling in MegaCD not setup according to this --> https://plutiedev.com/rom-header (check bottom for updated region handling in header).

we are talking md msu patches here and the header is patched to be region free so is changed to JUE
and mister is choosing the first region in the header on segacd
as i say though the fix is already in the github waiting for a release

Has anybody tried the relatively new MD+ MSU version of Ghouls & Ghosts on MiSTer yet? Before I go reporting issues to the author of the patch I guess I want to make sure I'm not alone in seeing issues. The coder of the patch admits that it wasn't tested on MiSTer.
I'm seeing constant freezing and locking. It's happened in various different places but as of yet I've not been able to complete the first stage because of it. The rom has been patched and renamed to cart.rom. The screen freezes and the game locks, music still plays & the MiSTer OSD is still functional.

i have had a quick go used the cheat version to play level 1 :)
and it seems ok but you also need to remember that msu is not officially supported by mister so they maybe problems with some games
i used the music by relikk if that makes any difference

I've tried both Relikk's "Arcade Soundtrack" and ArcadeTV's "X68000 Soundtrack" packs. Also, both cheat & non-cheat versions of the patch with the same results on every attempted playthrough. Rom patched with Flips, and my original rom CRC matches the readme.

Would have been nice to play this with the X68k soundtrack, but ... oh well, never mind! Thanks anyway, KnC. :)

Just noticed when looking through this, the region code stuff should probably be updated to reflect how it currently is in the Genesis core. The automatic header detection of region won't work right on any games that are technically following Sega's official methods.

https://github.com/MiSTer-devel/Genesis ... is.sv#L797

vs.

https://github.com/MiSTer-devel/MegaCD_ ... D.sv#L1046

Source for correct method --> https://plutiedev.com/rom-header - see bottom

EDIT: Also European region code isn't even supported at all in the current cart region code detection for the MegaCD core.

I'll test all this stuff out anyways, trying out other people's md msu stuff and see if I notice anything.

If you'd like to test with latest commit from shane, see if it fixes your issues. I just compiled it for you yesterday night.

Thanks for this build, aberu. Sadly, doesn't fix the issues I'm seeing with Ghouls 'n Ghosts. At this stage I'm going to have to assume it's something to do with the GnG MSU patch. I've just tested the author's Sonic 1 MSU patch & that's working perfectly.

I've begun testing these, but getting them all together and patching them is a real pain in the neck! Anyways, I had Moonwalker lockup for no reason at one point as well. Ghostbusters, Castle of Illusion, and Streets of Rage 2 Arranged worked fine for me for about 30 minutes of play each though. I have the default update_all bios.

Have you tested Ghouls and Ghosts yet? Do both you have the same CRC32 post-patch? This will rule out a problem with the patching procedure. I found that in one instance patching the MD+ patched rom worked and patching the original didn't, and in another instance the reverse worked, etc... Very strange.

EDIT: srg320 to the rescue! https://github.com/MiSTer-devel/MegaCD_ ... 8a9e4a698a

I'll compile one real quick to see if this remedies the issue for you.

EDIT2: Doesn't compile, needs to be fixed.

it does not do it every time i play it but i tried it again later and it did freeze so it seems random and intermittent on my end i played the first level like 5 times in a row and it did not freeze but later in the night it froze halfway through but then i managed a few goes with no freeze

Edit-- ahh you posted the fix while i was typing :)

Doesn't compile anyways, needs to be fixed, a new object srg320 put in there wasn't declared

Code: Select all

Error (10161): Verilog HDL error at gen.sv(650): object "DBG_HOOK" is not declared. Verify the object name is correct. If the name is correct, declare the object.

Been slowly testing these all out. So far every single MSU MD works for me quite well, except for Moonwalker crashing once, but couldn't recreate that after a few tries. I didn't play all the way through GnG because I'm just really bad at that game, but... Is this the hash on your patched rom?
