Great Work mic_!!! ... I need some of free time to test it!!!

Nice!!!

We only need a 65816 version, anybody?? The Glory awaits!!!

Hi mic_ !!! :)
I'm testing your Sixpack , and i like it :D

If you want it, fell free to include my version of the aPLib decruncher for MC68000 in it (with the modification that you comment for the lea (24,a0),a0 ).
And i think that my friend Metalbrain will not matter that you include his z80 ...

And you forget to tell that LOVELY manual in pdf that you added it!!!

Great Job, and thanks for the greetings!!!

I made get_bit routine faster, so it's better to use my unit. Also I add 2 preprocessors definitions. Size of unpacker is 212 bytes (Macros version).

It's old version of get_bit.
get_bit:
subq.b #1,d5
bne.b still_bits_left
moveq #8,d5
move.b (a0)+,d3
still_bits_left:
add.b d3,d3

Here's ...

I replaced BSR callings of .get_bit subroutine with MACROs and aPLib depacker became 1.5 times faster. Another replacement for .decode_gamma gives us improvement of about 1.075 times.

Yes, of course is the fight since the beginning of time "size vs speed" :P Well the first version used macros ...

So why not to put the corrected code here? I'm ready to test it.
Upss, ok i don't think it was necessary, because it was straight forward (change ; for | , and the most easy in the case of local labels was delete the . that precede them), sorry for the inconvenience, here is:

*** CODE DELETE ...

Well, i have downloaded the sdk that appears in this thread, and i make the modifications about the comments and local labels that Chilly Willy said, and don't get any errors in the assembly.

And now i am reading the GENESIS Technical Overview, i would like to try something.

Thanks!!!

You will need to change the syntax of the source code for GAS, adding a % before the registers,

Ugh - no. Sorry, but it's unnecessary. Add this rule to the makefile and just use "normal" syntax.

%.o: %.s
$(AS) -m68000 --register-prefix-optional $< -o $@


Great Chilly Willy!!! :D

I made ...

I love the arcade feeling of this game!!!

And i can see perfectly all your dedication to improve and polish the graphics and the music of this port.

Great Work!!!

Yes, it's how Stef said, gcc use the stack.

I found in this forum an example to make the necessary changes, in the files vdp.h and vdp.s in the archive mddev.tar.gz that appears on this thread .

Sorry for the delay in answer...

How much ram does it use?
Well, only need a few bytes in the stack for the return address of the call to the rutine and for the BSRs to the subrutines getbit and decode_gamma (nothing recursive)... well and in the case that you need to save the registers that i ...

Hi Everybody!!! :D

Shiru have suggested me to publish in this forum my MC68000 port of the aPLib decruncher, i hope that it can be useful for somebody.

The main features is that the decruncher are assembler source, small size (only 182 bytes), fast and good compress ratio.

To crunch files, you ...
