FULLVGA OCS 1fc,0: true for 30 years, real today!

[no_body]

Can the OCS chipset handle full vga screens? In short ... yes. Those with dedicated hardware will see that a handful of "new" lines of code show that the "old" amiga 500 OSC was ready from day one, ever since it was designed and arrived on our children's desks ... 2 versions: 3 bitplane 32x32 scroll (I still have to fix the pauses because on vga or pal the centering is obviously different), the other is a 2 bitplane, 128x128 pixel font full vga starfield sprites... also this impressive on vga. In better conditions and with help, moral support and sharing with you would have been better....

hope 2 to c u one day... i'm here...

Dear normal beings, I am sending you the first working version on OCS amiga and floppy boot, of the 3 bitplane fullvga with the sumptuous AXIS font I integrated. The differences compared to the code of the previous intro with the 2 bitplane are really many. I had to lighten everything and restart from just OCS to get a stable scroll without uncertainties or clicks. The third bitplane of the font drives the whole playfield crazy if I use the routines of the previous version. Meanwhile, I am satisfied with the record beauty of this fullsize version font! Note: JUSTOCSnfloppy boot! Sometimes works on others chipsets too but... it's the first version 3 bitplane scroll fullvga in life and "amiga scene". If i'll survive we could do something better together!?

Ok, the mix of size and aspect ratio between playfield, bitplane and
modulo generates a mix that is not solved by deactivating the AGA /
1fc, 0. In any case it is now functional on both OCS/AGA systems, floppy
boot. Some minor fixes and more stable source code also being tested
on OCS / AGA. You will find 2 versions with different scroll speeds
that demonstrate, apart from the blitter clicks, absent on the VGA
screen, that the scroll is rock solid!

So this Util will change Amiga output from 15khz to 31khz with its custom copper list?

Ok ... as I told you earlier I had noticed a strange click, different than usual deriving from the blitter. In these new executables you can see what I was referring to. If you upload the intro from AGA everything works regularly, a few lines of code very light compared to the previous version, however it means being over the maximum limit of OCS / 68000, loading is still possible, sometimes the OCS cannot "see" the scroll bitplanes correctly, but a reset is enough ... The upper part of the font is "conditioned" by the resources of the chipset / cpu.
The mix in the previous version and the startup seems to be compatible with all the amiga floppy/workbech systems on which I have been able to test but, I don't have all the amiga machines and variants .. some of you can do a try? (just4homosapiens hetero intelligent males or 2 female coders maybe in the world !?) c u...

Thread cleaned. No_body stop posting off topic random, and seemingly racist remarks (I'm unsure if it is racism at this point, I'll give you the benefit of doubt).
