I thought scanlines were inherent of all CRT based video due to how the frames are drawn on the screen, and whether they're visible (or rather, the gap between then) or not would depend on a variety of factors such as the focus capability of the Kinescope (aka CRT) and its wearing state, the...

I looked all over for these and could not find it anywhere... so I made my own: Here are the settings I changed to get the pixels as crisp as I could, starting from the generic profile: Video In Proc: Video LPF: 16 MHz Sampling Opt: Allow Upsample2x: Off (this made the video stop going in...

Been a long time dream to have a proper Model 2 Daytona USA board. Before I was finally able to bring it home, I set up my "poor man's Daytona USA" using a dedicated PC that boots straight to the game and a Logitech G29. I knew that the real thing though, would be much more complicated to get...

Yep, I'm about to order some shells and labels for myself, hit me on PM and I may be able to include what you need in the same order. About the multicart, Blio and I had a conversation a few messages above about that. Depending on the kind of solution it can be more or less involved. I...

I've tried doing that, and the game boots. However it does not accept any input from the Mega Play. I believe to make them work a ROM hack would be needed. If we're lucky, perhaps a BIOS hack could work for MD games. We miss you, @Apocalypse. If you want me to make you some cartridges, just...

It's a great start. I also found this on one of the manuals, which helps Having some of the IO work will help too. I'm thinking once I get it all figured out, I can probably create an adapter for common double analog joysticks like Xbox, PlayStation, etc. :)

I recently came across a Sega X Board (GP Rider), however it's board only. I'd like to convert that board but that's a topic for later. Right now, I just want to power on the board and verify that it is working. However I do not have a filter board, and I can't seem to find one anywhere. I'd...

I've ran into that thread a while ago. Unfortunately nobody has the modified BIOS and the link does not allow download, so I can't really test what it does. For all I know, it may just suppress the "Slot 1 cartridge not used" error, and he may have not tested if the game can be played (i.e...

With this flash cartridge you can load Mega Drive ROMs directly to it and they do boot without anything special. However, they cannot read any input from the system because it has the inputs mapped differently. So without some rom hack they wouldn't work on a Mega Play as it is different than...

Thanks to everyone for the kind words. I have my own rant about how expensive the MP related stuff is on another thread in this forum. The reset signal is the main issue when it comes to a cart that self programs from a SD, etc. Yeah I get it. A dip switch solution would work without it, it'd...

I just realized I forgot to follow up on how the cartridges turned out. Enjoy the pictures. Streets of Rage 2 got a custom artwork. The others are identical to the Mega Play originals.

Yeah, it's legit. And while a little part of me really wanted to get this so that I could provide a clean dump (the existing one is reported by MAME as a bad dump), there's absolutely no-effing-way any sane human being would pay that for this cartridge. Divide that price by 10 and we can talk...

No problem. It just coincided that I have been actively working on the Mega Play for the past month, and the reason why is in the other thread I just posted. I was coming here to post and I saw your message in there. It's nice when the stars align like that.

Hi all. I recently came into possession of a Mega Play board, but I didn't have the games I wanted on it (i.e.: Streets of Rage II). So I decided to make my own flash cartridge. This cartridge can be reprogrammed using a USB cable. It's not a multi, and it's not an EverDrive (i.e.: reads...

Mega Play is made compatible with the Mega Tech Cabinet because it was sold as conversion hardware. There was no "Mega Play Cabinet" but rather repurposed Mega Tech cabinets. I have probed all the signals extensively and you only get video output from CN8, which is directly connected to the...

Charles McDonald documents are legendary among all SEGA homebrewers. http://dreamjam.co.uk/emuviews/txt/s32tech.txt Very happy to hear about your project.

If anyone is interested, I wrote a blog post about how I went about measuring those.

I ended up measuring... And I guess what the heck, I built my own PCB because why not? This one could potentially be soldered directly to the board, or a classy header could be soldered into it as well.

Thanks. Yes I've seen those. I'm just wondering about the schematics because I could put something together and at least test the board properly before I decide if I return it or not, before buying any parts. But I guess I can pull one of those from the board and measure them myself.

To ship to the United States.
