What's new with theses carts ?
I use new PCB (Rev 2e) and flash chips that allow to store firmware larger that Action Replay firmware :
- Action Replay Flash ROM : 256KB
- USB dev cart Flash ROM : 512KB
It will be useful when making custom firmware for this cartridge
And, I'm now familiar with using flux when soldering ! Before, I was soldering small pitched parts (typically, the FTDI USB chip) with stain in excess, then using solder wick. This gave good results, but I wasn't satisfied with the visual aspect nearby soldering points :
And, there are now "ROM cartridge" available for sale !
This is just an "USB-less USB dev cart", but it allows to run Pseudo Saturn firmware, and also future revisions of the firmware with ROM size larger than 256KB available on Action Replay carts. And of course, it is a little cheaper than USB dev cart
