Quoted from Eskaybee:
3. Pinball browser question: started tinkering with it so I can get unforgiven and sad but true out of the game. I pretty much replaced the songs in the browser and changed the text , but tryin to mustard up the gonads to actually upload the .bin file into my 6500 game lol! Any surprises or any tips I need to know before doing the upload? Or is it as easy as it seems. And yes, I am reading the pinball browser threads but figured I'd throw this in while I do more research.
Do it! No worries on uploading the new firmware. I've done it 30+ times (while working on coloring frames) and only had it fail once. Recopied the firmware to the USB and reuploaded, no problem. Only takes 40 minutes lol.
