Doesn't start on pi 2 #67

Closed belab closed 5 years ago

belab commented 5 years ago

I'v written the image with win32 disk imager and copied the roms BASIC, CHARGEN, KERNAL, d1541II to the c64 folder. Once I started my raspi 2 the green led starts blinking in an interval with 7 repeats and hdmi screen gets a signal but it stays black. I tried renaming kernel7.img to kernel.img, which has the same effect on the screen except the green led is not blinking anymore.

Try formatting the disk, then use the bmc64-2.1.files.zip file and unzipping the files instead of writing the image. (Also remember to copy the roms again). If that workes, sounds like win32 disk imager did something strange with the partition. The results should be nearly identical except for the size of the partition. Let me know if that method works.

I didn't mention it, but first I tried this method. Same result. Is it possible to enable logs? What's the right method with the kernel7.img? Do I have to rename it?

I found it. I thought it was a pi2, but actually it was a pi1 model b rev. 1.2. Is there a way to run BMC64 on this model?

randyrossi commented 5 years ago

Sorry, the pi1 is not powerful enough to run without lots of frame jitter & sound issues. I don't support it.
