Mixed GPIO configuration

[dr-prodigy]

Hi,
for my setup I am using GPIO Config 2 (Real Keyboard + Real Joysticks, as per BMC64 PCB) with a custom PCB / harness (see #286 ), and everything works as expected.
Now, I believe a number of GPIO pins (if I'm not mistaken: GPIO2, 3, 9, 10, 11, 14, 15) are still unused in this setup, so I thought about the possibility of using them for other functions. More specifically, I'd like to add a reset line (like the one on the stock C64), but in my tests it looks like the GPIO custom assignments made on the GUI are not considered when Config 2 is active.
Does this make sense? Would it be possible to keep config 2 and still be able to configure the free pins as custom?

Thx in advance

Any comments?

I don't remember all the details but I think some of those pins are reserved for other purposes. Like 2&3 are for serial debugging. I think what you are describing is possible with some code changes though. Unfortunately, I don't have much time these days to develop features.

Hello
I really like this project as this was my first computer where I learnt to do machine code (Vic 20). So as nostalga I have started building one using my only Raspberry pi B rev2. I have an original keyboard and wanted to build a pcb to interface with the GPIO. And here is my problem, the GPIO pins used are not on my pi as it only has 26 pin headers and a second header . I have read it is possible to define which pins go where but have not understood how. I am not a high level programmer such as C, I can only do assembly language. Could yo help and show me how it's done?
