Re: Diagnose Broken Game - Metal Warriors

There's a big chance of the problem be just a broken trace.
You could try to check the continuity from the connector contacts to the ROM.
The CIC also has a good chance to have some broken trace.
There are information about the pinout of the connector and the ROMs here.
Hope you can fix it. :-)

Re: Does this song remind you of a song in an NES game?

That's a nice sound.
It reminds me of the action and adventure games from back on the day.
Specifically the keyboard sounds vaguely like some Castlevania sound...
Blood Tears maybe?
But different, with a kind of "futuristic" feel.

Re: SNES Mouse acting weird

AliExpress: https://www.aliexpress.com/item/1588006796.html That's a great deal! Unfortunatelly, since 1USD = ~5BRL the component costs a little more than 5 bucks to me, with the shipping costing a little more than 17 bucks. :-( The eBay seller infortunatelly won't ship to Brazil, I guess he was de...

Re: Help fix a NES Clone (Phantom System)

Sorry for this necroposting, but I still couldn't completelly fix the problem and got something "new". After I made a repro from a pirate board here I found that it gives the same controller problem in this clone. I also got AVE's F-15 City War and it gives me the same problem. So now I have 3 games...

Re: SNES Mouse acting weird

Microchip had a great reputation for sending out free sample PICs Tried with no luck. They ask for an institutional email, I tried my old one from the army and the university and both are dead. The city hall where I work currently has no corporate mail for now. :-( Alternatively, if you can muck up...

Re: SNES Mouse acting weird

Unfourtunatelly my programmer don't support any of these devices. :-(
I also didn't find them on local brazilian stores.

The one I found is Attiny2313a-pu costing 24 bucks + 14 shipping.
My programmer also don't support this one.

Seems a difficult case to me...

Re: SNES Mouse acting weird

So, no useful microcontrollers for now. Unfourtunatelly I know next to nothing about microcontrollers. :-( Would the PIC16F54 be good to go? I found one costing 10 bucks, but the guy isn't sending them right now. Wich one specifically I should search for? It doesn't seem much expensive, maybe if the...

Re: SNES Mouse acting weird

Ooops! So that's useless. :-( I'll try to find something else or a way to put a 40 pin DIP inside the mouse. Maybe cutting its pins it will fit, not sure. I've found an 80C51 that looks like an original MMC3. Not sure if I need to connect all the pins on the programmer to write to it, even less if i...

Re: Help with Kaiser's Highway Star repro

That's great my friend. :-D Thanks for taking your time on helping to solve this "mistery". Any chance to know the capacitor's value? It seems like a low pass circuit to help a little with the glitch. Do you mind if I post the pictures here? The board has a little different implementation of the map...

Re: Help with Kaiser's Highway Star repro

I finally found cart To test it out, The same is true of real machines That's great to know! It's confirmed that the clone is faithful to the "original". Thank you zxbdragon!! :-D If Fisher, my friend wants the PCB, I can send it to you. That would be really nice. You mean to send the PCB scans, ri...

Re: SNES Mouse acting weird

I'm really not sure if a DIP-40 would fit inside the mouse.
I found a PIC16C54-RC/P on a pretty bad PS1 motherboard.
Not sure if it works fine.
About the write process, I recently got a Genius G540, wich has this PIC on it's supported device list.
Is this one fine?

Re: SNES Mouse acting weird

I bet I could write a replacement. That would be awesome! Unfortunately the only 2 candidates I've found are an Atmel AT89C51 and 2 Intel 80C31. Not sure if they're suitable specially because they're 40 pin Dip ones. What would you recommend? Maybe I can try to "harvest" one or try to exchange with...

Re: SNES Mouse acting weird

Well, guess I'm busted! The pin that connects to the clock is acting very weird!! When measured with the multmeter with the positive probe on the GND it starts reading with with 1K, then goes up slowly up to 20K. The same happens when tested with the negative probe on Vcc. I tried to remove the capa...
