C16 and PET work: C64 Black screen.

[zBeeble]

So... I have my MiSTer all configured. C16 and PET work. C64 just gets me a black screen. Help?

[rhester72]

Does it still happen after a hard reboot of MiSTer? It's been black-screening for me lately as well (and nothing changed!).

I would first think of a corrupted file.
Have you tried to rewrite the core or/and the rom on your SD card?

[tomxp411]

Do you have an SRAM module installed? 32 or 128MB?

have you built the ROM file with the KERNAL+BASIC+DRIVE ROM?

[zBeeble]

I have at least 128M installed. This is across several complete powerdowns of the device as I rewrite the card. I have totally wiped the card and I have recopied all the files several times.

I have not made a ROM file --- I thought it was an optional step.

How about if you use the built-in ROM?
You can select Kernal: Standard C64, C64GS, or Loadable C64 ROM through the OSD.

To the point, the OSD doesn't come up. Blank screen.

it's a little surprising this story

here is my configuration that works for me!

It is better to transfer by ftp than by sharing smb

[LamerDeluxe]

Yeah, I've been having some odd problems with smb every now and then. Copying stalling and files that refuse to delete.

[zBeeble]

really? Can you post a config with a text thing? I'd really rather not download random .7z things.

[zBeeble]

So... I manged to determine that I had the RAM expansion plugged into the wrong header. Problem solved.

[zBeeble]

To Add Detail Here... I think the PET (and possibly the C16) don't require the RAM expansion. I'm still reading source, for various reasons, but I suppose the C16 and PET can use the FPGA internal RAM rather than the expansion?

[mklcolvin]

Does the C64 core require the RAM expansion? I'm trying to run it while I wait for my 128MB RAM to get here. Also, are the kernel, basic, and disk ROM files required, and if so, where do I put them?

Does the C64 core require the RAM expansion?

See here on the Wiki for cores that use SDRAM:

[mklcolvin]

Just a follow up to this: I received my 128MB SDRAM module this weekend - plugged it in, and the C64 core came up without any changes by me! So it seems that the C64 core requires SOME SDRAM to run. Same for MSX core.
