I'd like to make a custom checker/passthrought item. My goal would be to take the request command, issue a serial via usb message if I doesn't understand it, and do the same thing with the status command. In fact, it would help me to find unknown (or uncomplete) command while playing game AND to che...
By chance, does anyone know how is made a connector like USB ?
I'd like to make my own GG and NeoGeo pocket link cable because they cost almost the same price that the system itself but I wonder how to handle the metal part of the connector...

I was suprised by the rate of sync needed so I check the Menacer one, which should refresh at almost HSync rate. From Eke doc : The IR sync pulse is controlled by a RST signal, which in f...
It's mostly what people do. I was very surprised "port" were in fact "similar" games and not based on original code. It's something I can't do :( It's why my ports are so long to do....I first disassemble everything ;) Look at http://arhackde.spritesmind.net/ if you're interested ;) (which make me r...
post was perhaps more designed to be on Blabla but Step didn't move it, it's that he could accept it there,...so don't worry. I didn't realize it was the NES game. There is a lot of emulator and disassemblers or others tools, so it should be doable if you take this long road. I only was able to foun...
i suspected the first part but the second part, about 2 IR devices, is totally new to me. Thanks for all these details, very interesting. I get back to this subject month ago when I was studying if a wireless control was possible on MD. I was wondering which tech would be the best. good ol' IR ? blu...
It remind me of a game I need to finish to port... Enemy's AI is clearly not the easiest thing to understand....even more when you're RE it directly from raw disassembly. On the game I talked about, only a part is understood. How I made it ?IDA of course. It allows you to name var & func and see the...
From what we know, a CDD access takes almost 1/75s so every time a BIOS function called need to communicate with the CDD, it takes this time. Add the process time, you almost have a frame (60hz/50Hz) :arrow: you lost a frame every bios call ?! I don't understand how Sega let this happen.... At the f...
Reading for the 10 times the SoftDev manual, I realizead there were some CDD related registers. FF8034: what is exactly the spindle speed flag ? I doubt it define the CD drive speed right ? FF8036: I thought it was some read only register but it seems you have control over the HOCK, which drive all ...
