Cool scrolly effect!
Hmm, I rarely like these ‘fld’ stretchers, as the black lines mess up the logo too much imo. I love flex stretchers though…
Nevertheless, I kind of like this intro.
I like the logo y "fld" stretch effect. I also like the effect on the scroller…different. However, I just don’t care much about very many equalizer type effects. Overall, I like this intro though.
If it worked on a500 it is ok in my book.. all this newfangled stuff with kickstart 1.3 and 68010 and a1200 and what not.. pfftt.
Of course, back then when A500 was the standard machine, coders thought about cache issues on higher cpu’s. </sarcasm> 😀
I thought that one of the first thing they thought us when writing Amiga intro code is NOT to use self modifying code like we did on the C=64.
I remember it being explicitly stated that it would cause problems on faster CPUs AND screw the cache up. Which of course would cause a crash.
bobbearing: you can leech my fix here: stingray.untergrund.net/Amiga/SkidRow/bw-skidrow_fixed.exe
so, my question was : could you post the fix (galahad or stingray) which works with uae (or this source is good enough ?)
ps: another intro by Horizon have a bug under uae (this one – a playfield priority problem)
and another rare effect cant work with uae : vertical multi-resolution, used in menu/endpart of the game "Disposable Hero", and intro of 2000ad demo "runaway"
(and the famous "RAMPAGE" by TEK, but fixed i think, no?)
and Yes, Brainwalker intros are GREAT!
galahad: yes this could be true, at least it worked on some 68010/68020ec machines around..but as said above it was never coded for bigger machines 😉
stingray: the reason why it doesnt work on aga is, that it used a rgb-register that isnt supported by aga anymore 😉 thats the reason for the 6 bpl init.
The problem as I remember it was copperlist related, I think it was something like you generated the copperlist in realtime, but before it was finished, the intro had already been initialised. This wouldn’t have been a problem on 68000 7Mhz as the copperlist would have been generated in time, where as on the faster machines it wasn’t. But my memory is bad, it was a long time ago I fixed it 😉
BrainWalker: stingrays fix is for machines other ocs/ecs, but for these machines it wasnt coded, we even couldnt ever dream about them back in the days… Yup of course not. And no problem with that. I enjoyed the intro on my A500 back in the day (yes, I totally like it! :D) and it ran properly there. And I can understand BrainWalker since nobody likes to hear his/her 😀 code is crap or smth. And this intro features very clean code actually, it just doesn’t work correctly on no-ECS (i.e. AGA) machines. 😀 All other Amiga intros by BrainWalker I’ve… Read more »
bobbearing: yes maybe i was a little bit rough, sorry for this! but im really fucking up by ppl talking about things they dont know about and saying something isnt properly coded because it doesnt run on any emulator or any hardware that came out years later. think always about the year and the hardware something was coded in and for. this is not only for amiga but any other system. and for the intro itself: yes the original version does work on uae without any fixes, just the equalizer doesnt look as it was meant to be. stingrays fix… Read more »
Yes, correct. I did these fixes on and for a real Amiga back then. But I just checked my fix in WinUAE and it seems to work perfectly there as well. I only fixed it because I wanted to watch it on my A1230 I had back then. I didn’t care about any UAE bugs at all.
this site is becoming a true HELL
and I don’t think Stingray had made a fix for WinUae for this intro… and it’s seem to be the same fix… so what ?
it’s no more interesting to talk with all you, guys
i never said all theses things ?!?! :dozingoff
CALM!
i just talking about WinUae bug with THIS intro, no MORE !!
pffffffff
sorry, i didnt know back in the days that winuae will be the reference systems for amiga coding. just some thoughts, but didnt you think the 6 bpl init was meant to be so ? maybe uae doesnt work 100% as an original amiga ?
and yes the equalizer part doesnt work in uae but on the real hardware. is this now my fault ? uae doesnt support all registers and all my stuff was done for ocs/ecs machines….do i now must feel guilty ?
just some thoughts…
yep, it’s seems to be the same fix : in original equalizer bplcon0=$7200 and 6 bpl init, in fix bplcon=$4200 and 4 bpl init.
in the equalizer routine, bpl5dat and bpl6dat are initialized, and only 4 bitplans initialized in coplist…

what about this fix ? i tested original version and there are some bugs under winuae (equalizer, spritelogo), and this version seems to be ok
galahad: im really interested in this fix. what wasnt coded properly and on which system does it fail ?
This intro isn’t/wasn’t coded properly by Brainwalker in the first place, I remember this one because I fixed it, I will check it out because I’m sure my fix will enable it to work in WinUAE perfectly.
Fuck, apologies to Brainwalker, my use of English there was really bad, didnt convey in the slightest what I meant, reading it back, looks like I was attacking his code!!
🙁
its all fine with him, i did basically the same day for day, back in the glory days… so he sure takes it easy…
very first time i hear that logo for originals thing hehehe but hell who cares nowadays… so hows going you oldskool freaks outthere“???
Dark/Tcc Design/Red Sector did that logo in return he wanted an original game but never received that 🙂
Fantastic!! Good choice of chipper too, fits so well!! iN7!/Syn
Heya Brainwalker.. I like this one.. but WK is true when he said you have done much better 🙂
outstandig intro (as all Brainwalker stuff :D), fixed it for newskool Amigas some years ago. 🙂
Hehe… don’t get me wrong BW, I love some of your intros 🙂 Just not this one really…
the intro is not converted correct, theres a layer above the equalizer missing. uae cant handle this effect….but hell, again wk is against me…did i smell something ? ;))) but at all the conversion is done nicely…
I always liked those copper effects back in time, and still do… great logo, nice scroller and good chip tune… great intro
Didn’t like this one back in the day, still don’t like it now… decent flash conversion tho!
mmm.. Brainwalker
