miker Posted June 4, 2008 Share Posted June 4, 2008 Opisana metoda pozwala skonwertować kolorową grafikę trybu "MODE 1" i "MODE 5" z komputera Acorn Electron, BBC Micro i Amstrad CPC aby można ją było wyświetlać na Atari. The following method shows how to convert graphics "MODE 1" and "MODE 5" from Acorn Electron, BBC Micro and Amstrad CPC machines, so it can be displayed on Ataris. Powyższą procedurę można użyć wprost lub stworzyć dzięki niej 256 bajtową tablicę a do konwersji używać szybszej procedury The above procedure can be used "as is", or you can make with it 256-byte table, and the try to speed up that convert-procedure. In the source change "ekran" to "screen" and "bity" to "bits" - to make it more clear form non-Polish coders. ---- @Zylonbane: and now tell us about your first conversion. 2 Quote Link to comment Share on other sites More sharing options...
xxl Posted June 4, 2008 Share Posted June 4, 2008 > I mean i guess it can not be sooo hard no, it's not difficult, you also need this: http://atariki.krap.pl/index.php/Programow...k.C5.82adu_6845 ok. look: http://atari.pl/zalaga.rar with these conversions only problem is speed. you can convert most of the game from bbc micro (acorn electron) but they will not act with full speed. 1 Quote Link to comment Share on other sites More sharing options...
Bikerbob Posted November 5, 2016 Share Posted November 5, 2016 Yes this topic is old.. but does anyone know if a BBC computer could do galaga why we dont have one for the atari 8 bit.. I have been looking for this for a while, and found this thread.. OMG is it really that hard to make this game on the A8?? James Quote Link to comment Share on other sites More sharing options...
kiwilove Posted November 5, 2016 Share Posted November 5, 2016 I think the BBC version is Zalaga? And even this is not something smooth in movement etc. This game really requires fully independent sprites to do a decent version thereof - and therefore does not lend itself to this hardware. That you'll always fall short due to the hardware limitations. And even the pixels present (and colour limitation) are too limiting also. That you can't even do a mock-up that looks presentable. My thinking is - it'll be more worthwhile to do a game - that pays tribute to Galaga (reference back to it) but do a game that this hardware can handle adequately - so it'll end up being a variation of it and maybe introduce some original elements to it? It'll still require a programmer who's keen to put in the hard work that is necessary to pull it off - ie. make it work. And it will be a lot of work/effort involved. Anyone keen on such a project - need to get something working in a demo format - which shows the method/approach to pull it off. To show that the most critical part(s) are doable. If you don't end up with something worthwhile at the end - it's not worth putting in the time and effort to try pulling it off. I think even a version is lacking for the C-64 - which it's hardware can probably do a decent version thereof. Note - there was a Gaplus game that was done nicely. I'm not up to date with the C-64 projects/etc - so I don't know if anything was done from 2000? onwards. Like - I only came across the SNES Zelda game graphics recently that was put/hidden in a C-64 demo - Mythos about 10? or so years ago... And that is something I never expected to see running on the C-64. Harvey Quote Link to comment Share on other sites More sharing options...
holgibo Posted November 5, 2016 Share Posted November 5, 2016 Hi, there is a port of the PET Galaga. It was done by Norbert Kehrer 2013. Looks funny, but plays very good. PET%20Galaga.xex 2 Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted November 5, 2016 Share Posted November 5, 2016 Yup, the old playability point wins every time.....Jumpman, looks pooh, plays like a dream... This Pet game reminds me of something from the old ZX81 Quote Link to comment Share on other sites More sharing options...
Bikerbob Posted November 5, 2016 Share Posted November 5, 2016 Sooo I thought they did one for the 5200 and the 7800?? what hardware advancements does those have over the 8-bit?? James Quote Link to comment Share on other sites More sharing options...
BillC Posted November 5, 2016 Share Posted November 5, 2016 There is a version for the 7800, it has the more powerful MARIA graphics chip. Quote Link to comment Share on other sites More sharing options...
Bikerbob Posted December 20, 2016 Share Posted December 20, 2016 Just got back from a vacation where there was a Galaga/Pacman machine on the Cruise Ship - I did not play that many times, because I did not want to spend my cruise in the arcade.. but WOW I forgot how much I love that game. So if we cant have this on the 8-bit there are actual Standup emulators for the PC correct? IS there a correct original version of this game that one can play at home??

James The short answer is yes; and for not a lot of cheddar too. I have a Raspberry Pi 3 running Retro Pi hooked up to my main entertainment system. It plays Galaga just great, and lots of others too. They are the original arcade versions running on emulated hardware. 1 Quote Link to comment Share on other sites More sharing options...
kiwilove Posted December 20, 2016 Share Posted December 20, 2016 Actually this would be a good test game example for any game creator project. I know that it's probably asking for too much - but if it can deliver anything close - it'll show how good the game creator is... And such a game creator - needs to have lots of animation possibilities possible? 4 frame animation is nice, 6 frames nicer, 8 frames even nicer. The more animation you can put into any game - the better it will look. Complex animation can only be done when many frames are available - and the resolution needed to see what it is.

Mclaneinc Posted December 21, 2016 Share Posted December 21, 2016 (edited) Bikerbob, look up MAME (Multiple Arcade Machine Emulator), it has every flavour of Galaga, Galaxian defender and just about every other arcade game out there and almost all are perfectly emulated and don't need a mega pc to run them. Some classic gems that you may have forgotten etc, and the nice thing is that the clones are also perfectly emulated so if you saw it in the arcade of your local burger bar there's all the versions just as if you were on the machine. It has ports to just about every OS / Platform and the roms are regularly flooded on alt.binaries.emulated.mame (of course I'm not promoting any piracy here!) No person of the 70 / 80's should be without MAME, its a box full of good times...And its free And no, I'm nothing to do with MAME apart from a user no matter how much that reads like an advert Edited December 21, 2016 by Mclaneinc 2 Quote Link to comment Share on other sites More sharing options...

I know that it's probably asking for too much - but if it can deliver anything close - it'll show how good the game creator is... Agreed that it is a good test. Lot's of colorfull objects, complex moving, levels, design etc... Only problem imho is that we simply can't do proper conversion on A8... Compare these two (original and 7800 version): It just almost doesn't look like it's from the same game I wish we could do arcade like graphics but it's either hires or chunky color. Maybe there's still some kind of method to get more colors in hires but I don't know it yet... One more version could be chunky pixels but resized sprites or hand pixelated to be better than that 7800 port. 1 Quote Link to comment Share on other sites More sharing options...
+MrFish Posted December 21, 2016 Share Posted December 21, 2016 I messed around with the graphics some years back. This is a PAL type of layout. Considering NTSC, it'd most likely work out better with the score on the side -- as how Bosconian is being done. 8 Quote Link to comment Share on other sites More sharing options...
Brentarian Posted December 21, 2016 Share Posted December 21, 2016 Would the graphics match better if it was coded to use a vertical screen like the arcade? A lot of us have LCD monitors that rotate already, and for those who don't -- just tilt your head! ? 2 Quote Link to comment Share on other sites More sharing options...
shoestring Posted December 21, 2016 Share Posted December 21, 2016 Vertical shmups on arcade systems generally have the monitor orientated vertically. There's more of the playfield available and it makes the game easier to play. A lot of CRT monitors can be rotated also. I do that often with my 1084 when playing these types of games on my supergun. There's no reason why not to code it this way on home port, would definitely play much better. 1 Quote Link to comment Share on other sites More sharing options...

I did it also with a huge 21" IBM VGA monitor back when MAME and a few game roms still fit on a floppy -- with MSDOS. I rarely touch MAME these days though.

ryanmercer Posted December 22, 2016 Share Posted December 22, 2016 I still play my NES copy from time to time and last winter I played for a good half hour on a single quarter at an arcade bar haha. People were getting mad wanting to play and I'm like hey, I played this game hundreds of hours as a kid. 3 Quote Link to comment Share on other sites More sharing options...
popmilo Posted December 22, 2016 Share Posted December 22, 2016 Hmmmm.... mentioning G2f made me test idea of colorful hires. Found AGS (Atari graphics studio) on G2F site and used conversion from arcade screenshot into something called "HCI"... It looks like two combined multicolor pictures. Can somebody test it on a real CRT and let us know if it's good for anything ? galaga.xex 3 Quote Link to comment Share on other sites More sharing options...
