[Adventure II for Atari 8-Bit Computers?]

I just wrote a little article about this upcoming game,

i keep my fingers crossed for the final release

[Iso Hunters]

Steve Nicklin asked me for a source code, here it is:

http://www.mediafire.com/file/dektc5d5b4dxyde/isohunters.rar

 

Main file is called iso4.txt , all of the rest is linked inside.

Subroutine which draws playfield according to 10x10 array on $a200 is called "loop1" (loop2 does the same) . So I hope some of the code will be useful.

in case of any problems - gorgh at o2.pl

Agenda team will contribute, too, still working on it, should be sent at 31th

[Sillyventure 2k11 - winning demo?]

C-Drug has not been published yet. I've seen the demo on the SV and it trully rocks

[Iso Hunters]

no, it's only 1 or 2 players game. I considered the option to add more players but it would be hard for me to keep good framerate with more soft sprites

[Iso Hunters]

hi, the game will be available after some improvements in a few days (got to catch up on my job first) for both PAL and NTSC systems. Hope you will like it

[Intro 2011 - Source Code]

there was a GTIA mode textured twister in Ilusia.

Heaven: maybe put it on source archive

[A sine form scrolline - HOW?]

What Heaven said.There's also a sinus scroll example in MADS package.

 

Where? I checked the GFX folder of the exemples, but did not find it?

 

Thanks

Marius

Yeah, file is missing in a new package, here's a link to a file from older package.

['LXA' stable?]

yeah, definitely there are serious advantages of using illegal opcodes

['LXA' stable?]

 

do the same with 2 less cycles, or am i missing something?

 

yeah, good point, I guess I wanted to test Ilegals and didn`t noticed that it works slower, just missed that

 

Anyways, using SAX and LAX (f.e.) could be useful, but first one have to check if they work properly on different machines , it could ba a simple code that could be tested by the Harmony cartridge owners, I`ll try to write such code for A XL/XE .

['LXA' stable?]

here`s the code:

; soft sprite procedure
mix ldy #0
   lda $60,y  ;screen background on zero page
   ldx $a400,y ; mask
   xand #$ff
   ora $9800,y ; sprite shape
   sta $a300,y
   iny
   cpy #$90
   bne mix+2

['LXA' stable?]

 

Obviously the atari 8-bit doesn't have a vic-2 chip, but is it possible that something else might be putting data on the bus whilst your code is running that opcode? If it's happening in one place, and not another it sounds like it must be caused by something like this....

 

In that case Antic might cause this trouble. I deleted information that it sometimes works and sometimes not, because it doesn`t work at all, only if the accumulator is 0 the result is correct

['LXA' stable?]

Yeah, I checked it and it`s probably this opcode.I`ve used it cause The description I`ve read stated that It`s stable with $ff argument which excludes the influence of internal CPU register.

['LXA' stable?]

I used SAX ($87) and ANDX ($8bff; @ and X -> @), I`m not sure which one of them coused troubles though.

['LXA' stable?]

From my own experience with alari XL/XE I can say that Illegal opcodes ain`t called "illegal" for nothing. Even if they work on 4 machines, on 5th they will crash. In 6502 CPU case it`s mainly because there were many different models produced,so it could be the same with 6507. I used illegals in my game for soft sprite routine, and it worked perfectly on my machine, but then I sent it to competition and the effect was like this:

[homebrew games stuff on Facebook]

As the subject is close to my hearth (i`m working on my a8 project in a free time),i involved myself into this small project to get information about new games on various 8 bit platforms. So, if anyone wants to get some news or post links,here it is:
