This adds support for Beggar socket/Chisflash burner/Bunflasher (goes by many names.)

While it should support most reading/writing operations, there are stock firmware limitations when it comes to writing to Intel-style and Sharp-style flash chips. Buffered writes aren't supported and will slow down writing.

I will be releasing an MCU firmware that compliments this, and for those who want to solder headers to their device and flash it using a J-link style flasher, it will be available

Great job, I can confirm this successfully reads both original (very old) and flash GB/GBC cartridges, I have no GBA to try now.

Hello I've tried being patient and waiting for lesser Kuma about this but it's been well over a month lol(no offense Kuma I understand life and stuff). I have no idea how to compile this at all so I'm just genuinely asking here cuz I would like to test if this works on the GBA cartridges with the now called "chisburner" too lol. Edit figured it out lol. Rtc is not being read at all with GBA "chisflash" carts

Hi, I do not own this device, so I cannot test it. I would only accept pull requests of things that I can actually verify myself, because people will obviously approach me for potential issues, haha

If that's literally the only reason, I will personally buy you one as I said previously, and have it sent to wherever you need lol. It's a under 10usd burner I truly don't mind having to do that if need be
