Re: Very Interested

There is nothing to win with a high rank, nor access to hidden special thread.
So it doesn't make any sense...

it was my point of view, and why I never edited them.
(even if at, one time, I was about to create 16 ranks : from 1 to 16 bits ;))

Re: HDD (or flash) instead of a CD, questions...

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...

DIY connector ?

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...

https://img5.leboncoin.fr/ad-large/cb4a92d45691b3f0d9259be274b9ea9ce691ea4c.jpg Also found this unofficial one. 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...

Re: Monsters in adventure of Lolo

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...

Re: Monsters in adventure of Lolo

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...

Re: SEGA IR wireles joypad

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...

Re: SEGA IR wireles joypad

(oops, didn't see you post before today)

Got exactly the same at home.

What I wanted to trace/understand is how they handled latency ....
Have you any idea how they deal with it ?

Re: Monsters in adventure of Lolo

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...

Re: SEGA CD Mode 1

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...

CDD Registers

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 ...
