Re: Alien Ressurection has a cheat code to load code without a reset.

Awesome work! More than I could have hoped for. Is this similar to what UniROM does maybe? Just like the other swap disc you mentioned, I assume multi games burns would not work once the next disc is required.

@leafy Aaah nice one! Congrats on getting it up and running, If you're up for it it might be possible to play some of those games with the nocash unlock if you add a switch to your mod chip.

Alien Ressurection has a cheat code to load code without a reset.

https://www.youtube.com/watch?v=uRB7iUCX4KQ

Stopping the disc, no big deal. But this also allowed a disc swap then loading, thus burned discs load.

I wonder if this is similar code to the no cash unlock? The code would be interesting to dissect - if I knew how.

Interesting nevertheless.

I mounted the bin using ImDisk Virtual Disk driver, but Windows 7 and Windows XP can't open the image. Must I burn it, or is there another issue?

Re: Testing your MM3 pins, pin 6 is the data, pin 2 NOT LED

Correct, pin 6 on MM3 is the pin that sends out the SCEA, SCEI, and SCEE datagrams to fool the PSX BIOS when you use either a burned disk or disk from another region. So, yes, if you attach an LED you can visualize this activity... as long as the LED doesn't use too much current and there is enough ...

I use plastic grease at work for plastic gears in office equipment, so I had to chime in here. The white lithium should work ok, or anything synthetic without solvents.

Re: PSNee With Teensy++ 2.0

Nice, yet another AVR development board that can be used for SPI programming. Personally, I used bare ATtiny 45 or ATmega chips, and for those one needs to look at the Arduino schematic, the datasheet pinout, andthe PSNee source to determine the real pin map for the physical chip legs. I did find a ...

Re: PSNee V8 - Ultimate PSX unlocker

If you are going to go to the trouble of soldering in the modchip, I think it is fun to do a build using the individual components instead of the pre-made Arduino, but I understand the ease of the ready-made boards. I flashed the PSNee V8 to a setup on a solderless breadboard. All you need is; ATmeg...

Hi! I tried it on a SCPH-9001, and it works fine. :D I might see if I can use the internal clock method and remove the resonantor. On the readme when it said, "ATmega328(A/P/PA) @16Mhz, ATmega168(A/P/PA) @16Mhz" it gave me the impression I would see a schematic with the microcontroller, pi...

Great! Which programmer did you use to flash? I got a chip flashed using the AVR Pocket Programmer with the miniCore loaded into the Arduino IDE. I used a solderless breadboard with ATmega328P in DIP format to ICSP. I think it is important to note that your circuit assumes using an external 16MHz cl...

Re: UniROM 8.0.C - CartDetector, AR/GS V2 Support, ExHandler, etc

BTW, what does the PSX serial hardware do as far as logic, protocol, voltage levels... is it a RS232 implementation? Set your chip to 3.3 and you're good to go. In terms of actual setup (stop bits, etc) I'd say go take a look at the NoPS source: https://github.com/JonathanDotCel/NOTPSXSerial Thanks...

Re: [Help] PS1 don't reconize any CD

I need to leave until Friday, but it sounds like the sled doesn't move out. You should see more drop on SL- and the sled should move. Basically the driver chip sends a PWM on SL- or SL+ to turn that crappy little motor one way or the other. So, it is possible that IC is blown. The one I mentioned ab...
