Just a heads up for anyone else considering getting either the Mega EverDrive PRO or the MegaSD flashcarts for Mega-CD support:
I got a mega everdrive PRO and although it works fine on my normal megadrive 1 console on mega-pc it it very problematic - normal cartridge games have gfx glitches like missing or flashing pixels.
Mega-CD stuff do not work at all, you just get a black screen , no bios load or anything...
That's really odd as my EverDrive PRO works well on my MegaPC - and the SegaCD side works ok - I wonder what's caused the difference ? There are some things probably we can check to hunt down the issue.
1) the megadrive ISA board in my MegaPC is stock (bar the replacement of a couple of caps) - no region mods, or sound modifications. Keropi,it's a longshot I know, but do you have anyone nearby with a stock megaPC that you could test your Everdrive pro on - that would allow us to quickly narrow it down to modifications being a problem.
2) I had some problems with the version of the MegaCD Bios and it took a little searching to get one that worked well - probably not a discussion allowed here, but if you email me, we can have a chat about version numbers, and I can suggest a couple - and if it is the problem then perhaps we can at least post version numbers to help folk.
3) My Everdrive PRO is one of the first batch - and the firmware must be fairly early, and being lazy I haven't updated it since it was purchased. Next time I get chance I'll see have a look and if I can find any version numbers for both the cart and the firmware - perhaps something was broken compatibility wise in the newer versions of the firmware ? On the cart side, it might be worth asking krikkz if any of the electronics in the cart have been changed compared to the first batches ?
Hope that all helps - and will have a look for those version numbers as soon as I can !
