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...

Re: SEGA IR wireles joypad

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: Making Light gun for LCD TV

Since it's a subject I'd like to see an answer, here is what I found while doing my annualy google research :

this soon-to-be-available-on-store project uses wiimote, raspberry and video signal to activate lightgun by emiting light at the "right" moment

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...

Like this?
Like the one you described earlier with arduino, cpld and I2S DAC ;)

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 ...

Re: SEGA CD Mode 1

Another thing that bugs me..... The way the CD player is made on the demo seems difficult to handle on a real game. Let me explain : every command uses wait_do_cmd and wait_cmd_ack. These 2 are loops to check the communication flag. On a real game, a loop is a disaster. If your CD is dirty, every ac...

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

I was waiting for your proto ;) I'm still on it but on the soft side : still working on a ROM tester. My Mode1 ROM was working (until i break it yesterday), next step was to validate it on real hardware. If it works as expected, I'll add the way to send specific command one at a time to check CDD co...

Re: FPGA 5V

Great find !!!

So 2x (GTL2000 and 22 pullup resistors of 350ohm and 1 of 200Kohm for ref) + 5/3.3V regulator
