emkay Posted August 25, 2007 Share Posted August 25, 2007 (edited) Hi emkay, Could you please rephrase the last post? I had difficulty following the technique you were describing here... Are you running in Antic 4 (or raster mode $e)? or in Antic 2 (or raster mode $f)? It sounds like you are suggesting using maximum wide players under an inverted character/raster mask. If this is what you are doing, won't only players 2 and 3 be available at this level (since players 0 and 1 will overlay in prior 0 mode)? Maybe you could post the G2F file (if that is what you have used) to make things more clear. Thanks! It's Antic f (or 2) -> hires (32 byte width) The graphics are overlayed with simple PM in an object related shape. Perhaps "Inversion" was the wrong term here. It's technically more to keep the most part of the screen black. Edited August 25, 2007 by emkay Quote Link to comment Share on other sites More sharing options...
miker Posted September 4, 2007 Share Posted September 4, 2007 OK, for all who still waiting... The project is not dead - there are some minor bugs to be elliminated though. --- the modded Spellbound looks nice - any release date of it?

Heaven/TQA Posted September 5, 2007 Share Posted September 5, 2007 looks good. just a question... is this a port or is a z80 "core"-emulation running in the background borrowed from the speccy emulator? Quote Link to comment Share on other sites More sharing options...
xxl Posted September 5, 2007 Author Share Posted September 5, 2007 sorry, someone could translate this? to jest port i nie ma nic wspolnego z zxemulatorem. deasemblowalem jetpaca i po zmianach w kodzie aby dostosowac go do modelu programowania mozliwego do implementacji na 6502 przepisalem na atari. ciekawostka jest to ze jest to sposob w pewnym sensie powtarzalny - mozna go zastosowac do czesci spectrumowych gier - ograniczeniem nie jest jak w przypadku zxemulatora 16kb pamieci tylko sposob programowania na zx np. w miare prosty sposob mozna przeniesc ghost'n goblins lub jet set willy z zxspectrum ale juz np. knight lore (nie ma to zwiazku z pseudo 3d) wymga innego podejscia i nie umial bym tego szybko na atari napisac. wybor jetpaca byl zwiazany z portem tej gry na xboxa zreszta bedzie to slychac gdy puszcze gre w siec.

This is a port and it has nothing in common with ZX-emulator. I've disassembled the original game the rewritten it on Atari (after translating the code to 6502-assembler). The interresting fact is that this method seems to be repetitive and this is probably the way to convert more ZX titles to Atari. The limit isn't 16kB boundary (as it was in ZX-emulator) but the way of coding of particular game on ZX Spectrum (e.g. the titles like Ghost'n'Goblins or Jet Set Willy seem to be quite easy to convert, unlike Knight Lore which has to be converted using different method [not because of using 3D-graphics] and i wasn't be able to rewrite it in such a short time). I chose Jetpac because of X-Box port of it (you will recognize it after releasing the game). Edited September 5, 2007 by miker Quote Link to comment Share on other sites More sharing options...

Allas Posted September 8, 2007 Share Posted September 8, 2007 Really impressive! Now, I can't imagine what more can you add for the game. Is completed. Good work!, and a rare hi-res game color. Quote Link to comment Share on other sites More sharing options...
emkay Posted September 8, 2007 Share Posted September 8, 2007 Really impressive! Almost 30 years after the A400/800 was released, we see some really impressive hires game... Quote Link to comment Share on other sites More sharing options...
miker Posted September 8, 2007 Share Posted September 8, 2007 Ok, here are two videos of the last revision of the game (corrected FX and so on). One from the beginning of phase 1 and second one from its ending. Enjoy! jetpac1.zip jetpac2.zip Quote Link to comment Share on other sites More sharing options...
deathtrappomegranate Posted September 8, 2007 Share Posted September 8, 2007 This is very impressive work! As others have said, it's really not necessary to mess with the game format. However, the additional features will stop the ridiculous problem with the Spectrum original, that you could just sit on one platform forever and watch the score rotate again and again... If there are plans to release this conversion on cartridge, count me in! Quote Link to comment Share on other sites More sharing options...
miker Posted September 9, 2007 Share Posted September 9, 2007 Well, xxl just said that the game will come only as .xex file, but if there will be enough interest then the next two ZX-ports (at least planned): Ghost'n'Goblins and Jet Set Willy may come as cartridge versions too (even 5200 version is possible).

Tezz Posted September 11, 2007 Share Posted September 11, 2007 WOW that's really great work, recreating the Z80 code into 6502, I take my hat off to you, that's brilliant. Can't wait to see more titles converted. I would have loved to have seen them converted like that originally. The A8 scene is full of good stuff happening right now. I respect all the hard work put into it Tezz Quote Link to comment Share on other sites More sharing options...
Wrathchild Posted September 11, 2007 Share Posted September 11, 2007 I respect all the hard work put into it I'd echo that! What could be useful is a guide to mapping z80 'patterns' to 6502 equivalents, although I appreciate there's a lot more to it than that One day (in the far distant future at this rate ) I'd like to have a go at a Pokemon style engine and Pokemon Yellow on the GBC would probably be the reference.
