I'd be more than happy to give this a go, but there are three main problems: first of all, there's no guarantee you'll end up with a cartridge with a 5A in it - it could be a 5B instead of a 5A, as has been known to happen since they appear to be interchangeable. Which brings me to the second problem: whichever the case, you'd need to add in your own circuit to the Gremlins cart, because the top row of the chip (which is where the audio pins are located in the 5B at least) isn't connected to anything. Although I'm sure most of you lot could handle that part, it is far beyond my own capabilities (I'm a musician, nothing more). Lastly, I'm not exactly rich myself, and semi-rare Famicom games like these can cost quite a bit of money I can't afford to spend right now, so I wouldn't be the one financing this project I'm afraid.B00daW wrote:I bet testing an NSF with a Sunsoft-5A cart dongled to a TNS-HFC3 cart would be enlightening.
I do have a TNS-HFC3, however (it's in jarhmander's hands undergoing maintenance right now, but there's a good chance I'll have it back in working order). So if someone is willing to take the plunge and order one of these Gremlins carts, mod it and send it to me for testing, then sure I'll be glad to oblige - but there's probably not much I could do that someone with a Power Pak couldn't, anyway (swap tests etc.).
