Can somebody please give me a little advice in building own dcm? It seems Im unable to do so... Also some changes dont show any effect to the recompiled core. If this will work, Pong and some other portings will also work very fine on Minimig!
Thx

Hi Sascha,

Example in another thread.
Have fun! :mrgreen:

Hi Jakub,

thx for this example! Im already testing in other little projects

Due to existing ROM copyrights inside the core I will not provide this file to the public.
I do own a real C64 and its ROM chips.

Will C64 Forever help resolve this issue, when it is released?

I'm asking this because you can use kickstart ROMS from Amiga Forever releases on Minimig...

Excellent point! That should solve everything.

Problem is: on Minimig you have to store the kick.rom (kickstart image file) by hand out of any legal source to the sd-card for your private usage.
In fpga64 the core already HAS all the rom image in itself, no matter if one have the original or not. I dont know enough about copyrights to be sure of this situation. So please lets stop to discuss this matter.
Perhaps in time the rom image can be uploaded via sd-card. This will also free the fpga a lot to use its space for some other useful things

Would it be possible to some how build the fpga image without the C64 rom image then create a simple utility to patch the fpga image with the C64 image for use on the minimig before uploading by the user to their minimig?

sort of like a spatch was used in the past to update amiga executables as you cant redistribute the original fixed executable or library.

Unfortunately it's impossible because the fpga core file is a compiled binary file (including crc). Even with included rom image you will not find any of C64 rom fingerprint inside "minimig1.bin". Its all extremely translated to run inside the fpga as block-ram and logic gate components.

I may be able to store the rom image in s-ram by using an Amiga program. This would allow fpga64 to handle different C64 rom image and the fpga is not that loaded. It also would need to start the Amiga core first, upload the rom image to a special ram address and reboot Minimig with a different sd-card to use fpga64 core file. To make this work I have to reorganize those fpga64 rom module structure and to write an Amiga assembly program to pre-upload the rom image files.
Its all a bit complex to use but maybe the only way to release the core file. Pls give me time

Or you could throw it onto ThePirateBay and then wander into here innocently and say "Wow! Someone called Boing3999+1 has just uploaded a Minimig C64 core!" ;-)

Is the C64 core ready?

I need it, I want it! Give it to me! (the C64 core that is) :-)
