Atari ST to Amiga: Starquake Amiga Conversion

All the ancient emulators i've seen only run on 68000.

Even if one had some working emu for accelerated machines, the code itself might not run at all and you will often have timing issues (many ST games use the cpu for timing, yuck).

Thank you for reply. Yes 68000 and mainly kick 1.x
I belive chamelion II will run on 68020 but even less compatible.

Maybe so, but easy isn't challenging, so I guess i'll have to suck it up and try anyway.

Which leads me back to 'that' thread where you gave me a bit of a hard time over When Time Stood Still.... a little surprised that you haven't made a guest appearance in any new threads on the matter.

It is done now after all

I know it is probably silly, but... would it be even possible somehow to add to the game some special feature? I mean for example a tooltype in whdload icon that would start the game with C64 music. I know it was sid and it is less than compatible, but that song was just too good.

and smartbomb when screen is too busy

If you're interested there is a Nintendo DS remake with source code (C based) at http://www.karmatoad.co.uk/wp-conten.../Starquake.zip

@Galahad,
Another thing Paul Hughes was programming Starquake 2 which was never released, as a UK dev you may ask him
He may have the original source code of Starquake.

ZX spectrum gfx : http://www.icemark.com/downloads/fil...e_graphics.zip
and it's format :http://www.icemark.com/dataformats/starquake/index.html

Forgot to thank you for that, i've contacted Paul Hughes and we'll see where, if anywhere, that leads us

[kamelito]

No worries, that's cool, I hope you'll get the source code, Paul seems to be a nice chap.

Kamelito - StarQuake 2 that you link to does have much better graphics than the original ST version, however they are very dark (easily fixed though). All levels seem to be the same as the original game, so maybe after all is done these graphics (lighted up a bit) can be incorporated into amiga version as an additional option ?

StarQuake 2 does seem a bit sluggish though when playing compared to the original version, it is around 3 times slower when moving around. A bit annoying, since original ST version is quite speedy...

Loved this on the speccy! Good luck mate, if you want some music and sound effects for this, I might be up for it depending on when you are ready for it.

Well, perhaps i got mislead by someone who didn't believe in you at all by that time. Or maybe you just needed a small "kick" to finish it

[Predseda]

Are there any news?

[Predseda]

Still any progress?

[Bastich]

One of my favorite Speccy games
It will be awesome to have this on the Amiga
Looking forward to following its development.

[Subzero]

the only c64 game ive played hours for hours... loved it, and i love to see my fav hero is working on it, dunno if i already have mentioned this, you da Man , you Rock Galahad'ster

[Galahad/FLT]

Someone needs to put a leash on the Skid Rowdie

Well, i did manage to get the source code from Paul, and Mark Jones had some files and the ST map editor, but nowhere near close enough to the actual game.

So im just going to have to tackle it the usual way, also working on something else as well, will definately have to recode some routines otherwise it will be unacceptably slow.

[Strider]

This sounds awesome. Starquake was a great game.

Awesome !
Maybe the map editor is able to retrieve the datas of the first version if you manage to feed it right.

No, I believe its Oceans Map editor for ST, so nothing to do with Starquake

[Galahad/FLT]

Well, just an update.

As some will know, I use WHDLoad to help with development, as it quits on code that crashes, and theres no need to piss around trawling through the stack to find out what caused what problem.

For some reason I didn't use WHDLoad initially, because my Atari ST TRAP#14 emulator wouldn't work with WHDLoad because of code that needed to be relocated.

So I worked without WHDLoad. Took a while to get the emulator to work, but there was always some stupid problem, and serious crashes that stopped it working, but i'm thankful for that at least, because this is the most Atari ST system intensive game i've tackled, and having to learn what TRAP functions do and what not.

So, I junked the TRAP emulator, went back to WHDLoad.......... and had the game up and running in about 20 minutes!!!!!!!!!!!!!

All that pissing around with an emulator, and it caused more fucking problems than it solved. Typical.

I wanted to use Paul Hughes Starquake 2 code, but there was no actual game there, so I went back to the ST original.

And now i've got it working, and i've got the character moving with the joystick around the levels, it correctly swaps screens.

All i've got to do now is fix the dynamic pallete swapping, sort out the fire button for picking up objects, code entry in the teleporters, and then getting it to be a moderately acceptable enough speed on 68000.

So, after a little while of trying to make my life easier, I ended up making it easier by simply going back to WHDLoad and using that.

I also wrote a small utility for Amiga where you can load up an Atari ST .PRG file, and give it an address to relocate to, which makes life easier when it comes to patching the game and ensuring theres enough memory to run.

So far, the game is running in 512K, that might change to 1Meg simply because of music and SFX, will endeavour to get a video of it running on Amiga on Youtube in the next couple of days.

That is all, carry on

Nice to see that things are moving forward.
Keep it up!
