Really liking these Mega/Sega CD videos. Not very many of them around, and you provide great insight. When I get around to buying one, I'll remember to come back to these videos. Cheers.
where can i buy the eprom
Hi, can you tell me where does those gray and black cables from the connection board are soldered? I have a similar mega cd (also japanese) that has many problems, I repaired the power supply board, the tray has issues but most important, the connection board doesn't work (it has the same cables that go to the small board with the oscillator) and the main board doesn't work neither. I have a working sega cd and I've been swapping the parts to test it. If I use the sega cd connection board on the mega cd I get the boot screen with no sound or movement. Anyway, I wanted to know if those cables are in the right pins, somebody has been working on this console before me. Thanks!
Hi,
Can I get your email so we can communicate with email. I have the same model like you but what can I see is the sky logo and there isnt any boot animation. Please do watch this video https://www.youtube.com/watch?v=ShtUDRxMt04
I can send the mega cd to repair it.
You should replace those Stock caps before they start leaking…
I did this with my Mega CD 2, only I soldered a socket on top of the factory BIOS, piggybacking on the original chip, and I use a switch to flip between the original BIOS and the region free one.
Will this mod work with an un modified Japanese megadrive?
How did you manage to find a scart TV in australia? It's driving me nuts
Did anyone else hear Sonic Mania’s Title Music at 21:42 ?
Recently picked up one of these fairly cheap, hoping to do this mod very soon, thanks for the helpful upload mate, cheers 👍
how get aega mega cd region free bios link
Can this adapter do Saturn bios chips? Cheers
Is it possible to erase and reflash the original BIOS chip via GQ-4X ? Thanks.
Hi, I'm Stephen "Van Osdel" Barber, and I have a question:
If I had a Sega Genesis and Sega CD Model 2, you modify my system to be RGB Modded and Region Free?
Wait, so doesn't the MegaCD/SegaCD have copy protection, so like i could download and burn games without needing a modchip(apart from the region free bios that is)?
So if I install a physical switch to my genesis, would the only thing I need to do is to just solder the eprom chip?
@GlobalGarbage How much will it cost to have you modify a Sega CD Model 2 Console and make it Region Free and buy it back?
Works great with the newer GQ-4×4, that byte swap button is sweet
