Nice info. ;) Do you think there is a way to spoof the proper checksum by writing a lower number to the register, then only reading a small part...
btw, another thing I never got around to doing is seeing which signals the HOLLY chip actually disables on the G1 bus to prevent access to the GD...
Oh, actually, you can get away with replacing most of the stock BIOS I think, it's just the fact that it locks you out from being able to read...
Good question. lol
Yep - I saw the HDD patch a while ago, and that was cool and everything, but no details were ever released on how it was actually done. If it was...
@madsheep - thanks. :) I've had those datasheets for a few years though (since FamilyGuy or somebody mentioned the "Sega Packet Interface" one...
@dark - yeah, I REALLY need to make a new thread for the motherboard stuff. lol Sorry, just been so busy trying to get this final board...
Working hard to get the boards / kits released within the next 3 months if at all possible (for the Dreamcast at least.) I got the final-final...
Yep - for the "enhanced" version of the board (or the "Dreamcast Too", as I like to call it), we'll be leaving the G1 header on there. The good...

Yep - we're looking to get all-new PCBs made for the DC motherboard. I know I kept saying for years that I was going to finish that N64 mobo too,...
I'm now also migrating over to Altium Designer instead of Eagle. It's actually not too bad at all to get started with, and I'd been putting it...
I know I've said this too many times in the past, but we're STILL working on it. lol Sorry it's taking so long, but it's easy to underestimate...
Oooh. Never seen one of these before. Thanks for posting. ;) Can the person with the console PLEASE buy a USB Blaster, and read the code from the...
Hmm. Very interesting about the IRQ stuff. I did notice some weird stuff in the Vblank routine that may have been related to the CD drive too....
I've definitely heard that mentioned on a few articles, and possibly on a vid or two before that whoever had the prototypes were "supposed" to...
I'm thinking about backing it too tbh. I don't blame Dan at all for trying to get a bit of cash from this, and at least he is giving something in...
@ASSEMbler - I agree with that - Apparently, part of the original agreement between Nintendo and Sony was to make sure any and ALL prototypes were...
Oh dear - I can't get the BIOS to work under MESS with the debugger enabled - it just spits out errors? "Exception at EIP=7485B090...
Awesome stuff, guys. :D I will have a play with the BIOS now. @Cauterize - I didn't know you were on here, Adam. Thanks again for the article on...
