Re: Tempest is possible

Well - its only a decade of working on it because I am so slow and slack :) I am going to keep working on it till it is to the point it could have been a AAA+ game from the era of 8 bits :) NOW Making the UFO work the way it should. So in T2K (as it will also be in Defender) there is a list/array of...

Re: Weber's Rants (tutorials)

Normal 240 pixel wide mode will be 30 sets of 8 pixel. Each pixel is 6 clocks That means each 48 clocks for a not unrolled video mode it would have to Decrement a counter that starts at 30 (1 clock) Branch back to the start of the 48 clock section (2 clocks) Full unrolled is just you repeat the code...

Re: Weber's Rants (tutorials)

I'd think that any video mode (not unrolled) that previosuly relied on dec/branch to count tiles could be made to mid line uart if changed to int-ended-scanline.

you might need a 2-step unroll to get 2x1clk and 1x2clk extra time.

Re: Welcome Amigans!

I owned an Amiga 2000 with a bridgeboard. I did like that machine and I wish I had of kept it.

Was what I wrote my first 68K assembly on.

Re: mmc_lib vs Bootloader V5 vs PFF vs FatFS vs sdBase(sdSimple)

Yes it is all C callable. It was mostly written in C to test functions and then converted to ASM for speed. The C functions are in the comments of the ASM I personally would say "the best" is a combo of Jubatians great bootloader for doing the card init and file system stuff - then only us...

Re: Tempest is possible

This weekend I am going to add proper behaviour to at least "UFO"

I will show how that is done here as that will be a precursor to anything Defender. That new game will basically borrow the object handling architecture from T2K.

Re: mmc_lib vs Bootloader V5 vs PFF vs FatFS vs sdBase(sdSimple)

Looking at a file I have here called sdBase.s it looks like my writing style. I don't know if that is just a modified one I did or if I am the source. Anyways the thing I have is hand tuned assembly to get absolute fastest reads possible. The thing I have should be in the T2K source zip file which y...

Re: Stopwatch

I made up that other number. This I think is the real number. 1820 clocks per line 262.5 lines per field 477750 Clocks per field 28.636363 Mhz 59.94 Hz or pretty close You could just use the frame counter and divide that by 59.94/60 If I used TCNT0 or TCNT2 myself - I would probably not try to do it...
