Re: C64 core - help me get it running

this is the only core I have an issue with. I load up my ao486, aga, and more. All work fine on the monitor and SDRAM. You don't need boot.rom at all to run the c64 core, it's only for running custom kernels like jiffydos. Try removing all boot.rom files from your SDcard ( in the root and the C64 d...

Re: MiSTer Fan

Ok you mean you are running this: https://www.amazon.com/gp/product/B00NEMGCIA And to connect to the MiSTer the fan you just used the 3 pins to 2 pins converter included in the box of the Noctua fan? Or you made some special wiring? Yes that one. I removed the yellow wire and shortened and crimped ...

Re: MiSTer Fan

I tried now this Noctua Fab 12V fan: https://www.amazon.com/Noctua-Cooling-Blades-Bearing-NF-A4x10 And it doesn’t spin. I use the 3 pin to 2 pinch converter inside the box of the Noctua fan but it doesn’t spin what could be the problem? Maybe, I need strictly a 5 V or 3V Noctua fan? Thank you I’ve ...

Re: C64 Core

I think bertnorg is talking about the secondary mode of the 1351 mouse. If you hold down the right mouse button while the c64 is power cycled the 1351 mouse works like a 1350 mouse which just behaves like a joystick ( ie not using potx or poty ) Then you can use the mouse for software written for po...

Re: Compile c64 source code for MiSTer with quartus 18.1.

If you haven't compiled a core before, have a read of the Wiki. Take note of the Trial vs Full on RBF's. https://github.com/MiSTer-devel/Main_MiSTer/wiki/Core-porting-notes#fulllite-revisions Hi good afternoon. I compiled the source code of the C64 with Quartus 18.1 last night. The quartus shows 100...

Re: C64 Core

This is probably a completely useless bug to implement in the core . . . . . . but the T65 CPU doesn't seem to implement the page boundary bug for shy and shx illegal opcodes.

Re: C64 Core

Isn't 128D keyboard too bulky? MiSTer board is very small. It can fit into C128 case, so no cable resebling 380V power cable required. Yeah, but I like the chunky terminal style of it and it has a different feel to my C128s and C64s. I’m thinking I’d like to mount it all in a scaled down box to mat...

Re: C64 Core

I've tried it out and this code works nicely without modification ( although I did move some pins on my Micro ). https://github.com/dabonetn/C64USBKey/blob/master/C64USBKeyboard2.ino Right Shift and the F-Keys give you the Even F-Key numbers Left Shift+Restore gives you the F12 Menu.

Re: C64 Core

Hmmm . . . I'd like to do the same thing. I have bought a 128D keyboard and an Ardunio Micro ( with the USB host support ). I just need some time to wire it up. Maybe I'll move it to the top of my project pile. I thought this might be a good start, although he's mapped Shift F1 (C64) => F2 (PC). htt...

Re: C64 Core

Does Wizball work for you guys in the latest version of the core? It seems to hang before the tittle screen. Game was working with older versions of the core. Could it be a regression? Or maybe the dual SID somehow confusing the game's code? The last core that wizball worked on was : C64_20190128.r...

Re: C64 Core

Hmm that explains why the VICE test suite for the CIA has Old CIA and New CIA tests in it.
I’m guessing the Lorenz tests were only written for an old Breadbin. Maybe these tests would be a better benchmark.

Re: C64 Core

In the source for the 8580 sid_voice.v, if you set default to triangle in the waveform selector, then the music plays for GUTZ and Hysteria with one slightly odd voice.

Yes I know :( but I took the time to find it and at least I tried.
Now someone else better than I can implement it properly.
That’s all that matters, isn’t it.

Re: C64 Core

Great! I'll test it. Didn't you try just to remove "enable" from the int firing logic? That way it still would not have the interrupt delayed by 2 enable cycles, and no need to use the falling edge. No didn’t try that, I’m not that familiar with HDLs in general so I don’t know of those ty...

Re: C64 Core

can anyone try Turbo Outrun on the C64 core ? I was wrong! This morning I tried Turbo Out Run on my Ultimate 64 and behaves the same way as the C64 Core on MiST/MiSTer. Hysteria instead plays perfectly on the Ultimate 64. Is there space for improvements ? I've fixed the music for Turbo Outrun. I'll...
