Hi @ all,

today I should receive my Minimig shipping, I am very excited :)

for all this modifications in the minimig core (FPGA Firmware), i also want to test and try something out.
question is, how to compile a single module into the whole minimig1.bin file??
is there a freeware compiler available? do i have to translate the whole source again to insert a single module?

i am sorry for looking stupid to you, this is my first try in doing something like that. until now i did only code some little intros in m68k assembly.

please help a bit, minimig is a fantastic project :)

regards
Sascha

@yaqube
What changes did you make for the 50/60Hz switching?
It acts like a PAL and NTSC machine, but some games and demos/intros then show different graphics effects.

e.g. an old cracktro from Blizzard works fine at 50Hz. switsching to 60Hz will "destroy" the objects and scroll text.
switsching back to 50Hz everything is back to normal.
the same is even when booting up at 60Hz and then switsching down to 50Hz. its the mode itself what causes the graphic trouble.

perhaps we can combine our research to find the general problem that also make other games and demos show that graphics problems all the time.

This video filter idea is impressive, looks like a bilinear filter, very useful für large TFT screen :)
how is it made? please tell us :-)

@Darrin

Minimig IS an open source project, due to the GNU licence anyone has to make the source code public to a released binary.
It is the same as in Linux, exceptions are commercial products and they have to be declared as such.

I am also not happy that this source is not available to the community, that make it sound like closed open-source! Anyone wants to make the nice minimig working more perfect, so all improvements should be open to anybody :-)

Regards
Sascha

And I know what you are saying ;-) in fact I also can not do very much with the source but certainly other ppl like Dennis etc.. They would be as happy as we are to see any new source.

I am also trying to compile the source and improove something (as blitter things). When I did something, I will release the source in the same time. Maybe somebody else can do more with it.
