I don't think this module will help you any way - it's not for TAP files.

Wow impressive Work. Can't make a New Build here (not at Home) and browse the code with my Cellphone. Thank you.

Re: Commodore PET FPGA source

Gehstock, I've made more cleanup on my repository. Now it should be more easier to understand. About tape support: First TAP file i've found for PET is 260KB. It means, you cannot use FPGA memory anymore since it's not enough. I've added my SDRAM module i'm using in other cores. Since FPGA RAM is en...

modified version is here: https://github.com/sorgelig/Pet2001 I rewrote the video completely. Did some code cleanup, but it still needs a lot of cleanup and optimizations. There are some signals used as clocks and should be fixed to avoid the bugs later. Why you use sd_* signals and sd_card module? ...

Re: ZX-UNO Spectrum FPGA

I know the original next186 core. I even tried to port it to MiST, but stuck on one place. Also i had no good environment for true VGA output.
Well, if port will be released in source code, i will try to port again. Original version uses SDRAM.

Re: MiST inside Amiga 1200 case with keyboard.

CD32 games seem to work though. But they are in WHLoad format, perhaps it worked on both systems originally. WHDLoad app provides some level of emulation. CD32 has Akiko chip providing chunk color mode. So WHDLoad adds emulation for this chip. What is your definition of "real demand"? rea...

Re: MiST inside Amiga 1200 case with keyboard.

My version above is more cleaner, IMHO. But both logics are acceptable in general case. You always thing like it used in Amiga. Other cores aren't exactly use this key as caps lock. I don't remove keyboard functionality at all. It will work as genuine ANSI Amiga keyboard. Tell to US/UK ANSI keyboard...

Re: MiST inside Amiga 1200 case with keyboard.

It will work only if you won't pass Caps Lock key till it released so you can tell if any other key was pressed and then quickly send press-depress events when caps lock released. I know this trick, but it won't allow core to use caps lock as generic key. That's why i've said this logic won't work (...

when you press Caps Lock it's already sent to core, so your logic won't work.

Re: MiST inside Amiga 1200 case with keyboard.

An Arduino or Teensy is more than capable of reading the keyboard matrix themselves. Of course they can. You only have to find 31pin FPC connector. Good luck with that ;) It would be very easy to solve the F12/NumLock problem too, by using Caps Lock as a modifier key to generate the "missing&q...

Re: MiST inside Amiga 1200 case with keyboard.

The Amiga community is quite strong, I find it strange that nobody has created a solution based on a Teensy or Arduino or something. As stated above, if you connect A500 keyboard controller to A1200 keyboard, you will have arduino option. It will be more expensive (if you don't already have a spare...

Re: MiST inside Amiga 1200 case with keyboard.

If Amiga keyboard would provide more keys, then i would happy to add support for all layouts. The fact is: Amiga has less keys than PC, and there are other cores for MiST requiring PC keys missing on Amiga keyboards. I cannot change this fact. I just had to comment on this... How would you write a N...

I am sorry, my language is Norwegian and I use Norwegian keyboard layout, the locales on my Amiga setup is also in Norwegian, and those keys are used for shortcuts in Workbench and elsewhere, there is just no way I am "downgrading" to US layout. I didn't know that US layout is lower grade...

Re: MiST inside Amiga 1200 case with keyboard.

Amiga keyboard misses some PC keys, and MiST is not Amiga-only emulator. So these 2 empty keys (on US/UK layouts) are very important. Right becomes Right Ctrl, while Left becomes Fn key. Without Fn key you even cannot switch between mouse/jouystick emulations. There are many offers of UK/US A1200 ke...
