I might, but I'm at work right now. If nobody else beats me to it, I'll have a look when I get home.

I've got experience with programming in C, not much NES experience but a fair amount of Mega Drive experience. I recently formed a software/game development company and require some small projects to build some initial revenue to get off the ground. If you could PM me with some details, or some exam...

Well, may I suggest that you use the PCBA Consultation service from iteadstudio.com? They manufacture boards rather cheaply, and the PCBA consultation service based on gerberfiles and a BOM will respond quickly with a quote for fully assembled boards (yes, with parts on it) in the quantity you spec...

Do we have a clear idea on how much current is safe to draw from the cartridge slot?

This is obviously an important consideration in designing an expansion.

Thanks, it works properly now, I just need to get midi hooked up.

I must've missed the part about enabling SRAM in the header.

I'm having trouble getting this working, I applied the patches in RetroArch, used a copy of GEMS 2.0 (I have the Megadrive ROM and PC software for this version, dated 11/21/91. Anyway, I setup the Fifo, configured DOSEMU to use it for LPT, and ran the gems rom in the patched retroarch, some communic...

That appears to be filtering to allow the graphics to appear closer to how it would on a traditional CRT TV. This is a GOOD thing, it's not an 'ugly' filter. It allows for visual effects that depend on it, such as the transparency of the waterfalls in Green Hill Zone to function correctly. Example: ...

I'd prefer if one of these devices was built to run a custom lightweight linux distribution with a good boot splash, and it should auto boot into a full screen application with a game-console user interface, similar to XMB or Xbox Dashboard. That way, it'd be more usable as a game console, and seem ...

Just so you know, my loader (Luke_ProjectCD) does still have some issues. It's mostly okay for an application that will start and then never touch the CD Hardware again (I left Columns running for a few hours on a EU Mega CD Model 1 to test stability) however, as it doesn't trigger the correct inter...

I can understand if you do not wish to share it, but it would be a great help if you could post the source code to your test application, that way we can attempt to diagnose the problem you're having.

ob1, has this been verified on real hardware, as Chilly Willy's post above states that he couldn't get the FIFO DMA to function without some data loss?

68K to SH2 DMA FIFO

So, I'm working on a 32X project and have been for a little while now, and I need a method to transfer a large amount of data (Too large for the communication registers, possibly up to around 600 bytes) to the SH2 from the 68k. I read that there is a DMA channel for 68k-SH2 transfers but I have no i...

Starting the 32X from Sega CD

Firstly, I apologise if this post is badly written, I'm quite tired and I'm not too good at asking for things anyway. I've already wrote my own bootloader for the Sega CD, that loads an executable into the shared Word RAM and runs it, so I'm fine with the Sega CD side of things. How would I go about...
