- Reward if someone can find why (when) a "B" is displayed on screen sometimes (rare) or we get 4 lives
- An icon would be nice too

The normal zipfile is blank (and I have no idea what to do with the HD one)

3.5 icon is OK, 2.0 is corrupt, can't change it or save it back.

It needs all chipmem you can get. On Winuae I had this error, reduced chipmem and now it runs. But I suppose that if something is loaded at startup then it won't.

TCD · 30 May 2023, 07:48

Just had a quick go (A500 most common quickstart worked for me) and except for 'possible graphical glitches (stars)' (they 'bleed' out to the right randomly) there were no problems

I just suck at the game

Well done Jotd !

Another great Arcade Conversion for our Amiga

Working fine with Winuae, except for the occasional gfx glitch here and there..

Likewise matching with my real a500 using Gotek and c0pperdragon's RGBtoHDMI option. Although I had to change TV Aspect ratio from 16:9 to Screen Fit on my Samsung TV othewise it would cut off the top half of the screen in HDMI mode

Seeing I can run two signals at once with c0pperdragon my 1084S at the same time is providing a proper picture

Thank you very much for this !

Loving the game.
I have also tested it on pistorm32, unfortunetly the game runs way too fast (at least twice the speed if not more) regardless if I check or uncheck the "Slow Machine" whdload option:

the pistorm speed issue is unexpected, as the game is synced with vbeam. Did you try Xevious or my other ports?

Did anyone experience stars glitch on REAL HARDWARE? (I'm aware of them on WinUAE)

(the 1084S pic with galaxian running is super nice!)

Yes, of course... Xevious (and all other ports too) runs with proper speed, the problem there is a stripe accross the screen where the sprites/bobs are not shown (if you remember I posted a video in the xevious thread).

It is strange that it runs so fast even though it is synced to vbeam.

Star glitch is present on pistorm32 too...

Yes.. side by side with HDMI and RGB (on the 1084S) the gfx glitches happen at the exact same times on real hardware.

Yeah, I remember. For Xevious did you try the latest version? Because I had fixed double buffering switch after you posted your video.

I don't understand the speed of Galaxian. Even with WinUAE and fastest as possible setting, it runs normally. I'll think about it...

ransom1122 · 30 May 2023, 14:52

I was only talking about Galaxian, I will try xevious on real hw tomorrow

Yes, tried latest version of Xevious and the same problem with dissapearing sprites line as before is there.

jotd · 30 May 2023, 15:14

damn. Any problem with any other games?

Pac-Man : Here and there problems with sprites (check video)
Ms.Pac-Man: No problems noticed (not played that much)
Scramble: No problems noticed (and played a lot)
Super Cars 2 AGA: No problems whatsoever
Xevious: As noted before the invisible line

Amidar: Using TUDE DEGRADE before running it is pretty much perfect

I didn't mean the games I've worked on in particular, but also other games.

But Pacman & Xevious & Galaxian issues are serious, yes!

PS: I see that you have a nice AGS configuration with all new titles !

There are other games with problems, of course

But with latest releases of firmware there are less and less. It is a JIT implementation which is where problems lie (SMC) and there might be a bug or two somewhere in some instructions... but generally games run ok. When testing A LOT of games these are the problematic ones I have come across:

I love AGS, have customized it til it hurts (even though I hate E and if I had time I would convert it to C

).

jotd · 30 May 2023, 16:50

oh you can change stuff in AGS? Great. Because for me pics only show if I'm using PFS. On standard FFS they just don't show...

About your list, I'd say a lot is caused by JIT. And you have flickering and all... I don't use self-modifying code in my games, but I can certainly test them with WinUAE JIT on, see if there are similar issues

I only use PFS

But they show up in WinUAE when mounting a directory without any problems... There was a source release a while ago and I just went from there

Uses usual Amiga OS calls for stuff.

Some work with WinUAE JIT, which is a bit better at detecting SMC and flushing cache it seems
