Next ST game port : Oids

As the title says, i've just made another game port from the Atari ST.
It can be found here : meynaf.free.fr/pr/oids.lzx

It was hard to find my way ; this one had TOS calls scattered everywhere and even GEM calls (trap #2), in addition to a very messy keyboard handling code, file i/o storing 16-bit handles where it should have not, and a fearsome protection scheme which i am not even sure to have fully removed.

But here it is. As i never played that one on the ST (and have no PC to run an emulator), it would be good if someone with a great knowledge of the game could test this version, to see if everything behaves as it should.

I'm not too confident with that one, many bugs are probably lurking in here, ready to explode in your face - so beware. Only thing i can say is that it seems to work for me.

I don't think i'll make any more game ports, at least for some time. I now prefer writing my own game from scratch.

Omg... GREAT conversion (after 5 minutes of play) ... what are requirements ? It seems it won't work on 68000, just 020 and up ?

Good decision. I`ll test your port later and report.

Bootable adf in the zone.

As usual, this is very unofficial, don't bother Meynaf if this doesn't work on your Amy.

Thanks meynaf, looks really great. But you can't shoot via joystick fire button. Any chance that you fix this?

Yes I could fire either with the joystick button, also scenary was also missing or moved above from were it should be, now mind I was running this on uae4droid under a1200 wb3.1 standard settings, but its 95% there so far, maybe that security you mentioned is causing this ?

I don`t know the original game. Here on A1200 040/40 gameplay (movement) is stuttering. Ship reacts a bit slow. Joystick fire doesn`t work but keyboard fire works. When I hit fire the ship moves forward (shoot direction). So the ship moves into the opponent you want to shoot. I guess the opposite would correct.

I made a table about comparison (ST version and this port).


And,
"Hoppoids" Galaxy didn't exist in the original retail version, did it?
Do you know detail about this Galaxy?

PS.
At least I played all stages of "Novoids", the easiest Galaxy.
I did not come across any glitches,so I am happy.

Great! My favourite Atari game, finally on the Amiga!

But here it is. As i never played that one on the ST
I played it a lot over the last 20 years and it looks quite good for the first version.

Some issues I noticed:

- The title screen / menu / highscore list background is orange. In the original version I remember it was grey.
- The whole change key selection window is flashing red.
- You cannot assign the Ctrl/Alt/Shift key there.
- Menu item [CHANGE KEYS] remains grey after leaving the function.
- Problem with keyboard handling in the game. I use cursor up for thrust, left for turn left, right for turn right. When pressing those keys fast or at the same time they get stuck (ship keeps turning, for example).
- When playing with joystick the fire button doesn't work. I have to use right-shift instead?
- After pressing Q in the game the whole Y/N requester box is flashing red.

Will continue testing over the weekend.

there still only one game i would like to see on amiga, it's karateka.
But it's sure, it's better to make a new game.

The only real issue is from the moment keys register. The shooting of cannon for example should be an almost instant stream of bullets the moment you press the key but this is delayed for about half a second. It's quite a breaker really

Not that I'm not grateful for the effort done on this at this point

Anyone that has played a lot of Oids will know that joystick is actually a bit awkward in truth compared to keyboard. Shield has to be applied on and off rather than simply depressed and quick shield recharging requires you hold down the space anyway when using joystick. This sort of game just suits keys like Asteroids before it
