Conversion Capers: Rygar

From Invent, I've got Round1 and Two maps made with Tiled. I'm working on reading the new file format. We're working on 64 colors!

that's awesome !!!

It's great to see that this is still coming along nicely.

Keep up the good work

I'm looking forward to the next preview. It will be interesting to see a version using EHB graphics!

It should be possible anyway, the only real question is how to deal with the increased time spent Blitting while having less time available to blit in. But then again, maybe it's as simple as merely limiting the amount of enemies you throw at the player at any one time.

A very quick update.

The attached image shows possibly a sneak peak at palette optimising. The HalfBright version is the optimised image.

It will certainly be an impressive achievement if this game can run at 50fps with 6 bitplanes combined with the sprite reuse for the background.

There must be almost no time left for the CPU after all of that DMA has happened.

Can't wait to see how it goes.

I hope we can do it! We'll do some test to see if we can archive this!

That looks pretty good! Can't wait to see more!

Here's hoping that this HB experiment succeeds. But frankly it would "just" be the icing on a very tasty cake ;P

It's like a developper's diary. Interesting to read. Seems I would take more than one evening to read it all.
Edit : Is it an OCS or AGA game ? -> I can't acces the Zone (yet?) to download latest test executable.

First page for latest exe : Sandruzzo's google drive link

@Foul : Merci

[jotd]

very good! I didn't find the "jump" controls, otherwise, looks very promising.

That's really too bad that US gold did crappy conversions of games with too high specs instead of doing perfect conversions of games that were possible... Maybe it was too late when AGA went around.

It's the 2nd joystick button jotd

If using WinUAE with "Keyboard Layout B" then it's <Right Shift>.

Freeze at start.
My config :
Amiga 500 KS1.3 (real machine) 512Kb Chip, 1,8Mb FakeFast

Everything stay static and correct except bobs are corrupted (garbade datas).

Edit : Launched from Wb by clicking icon. Same result as Damien :

Ghouls'n'Ghosts is currently adapted from CPS1 to Atari STE by Anima.

He has disassembled the 68000 arcade code, and made some modifications so that the game can run on Atari STE.

Until now, the result is excellent.

The machine target is a 4mb of ram STE. He has found a very good 16 colors palette for the game.

The main problem with CPS games U.S.gold has converted, is the amount of ram needed.

I'm sure that SF2 original code could be too patched and running on A1200 from the original arcade assets and program code.

I had a look, his work is incredible with the palette.

Palettes were always a major problem with CPS and games, and even later 16 bit ports. At least on the Amiga you have the copper and sprites to give you some extra options. I'm always amazed at how good games using dual playfield can look when a skilled artist is involved.

I think games like SF2 that really need 60Hz refresh might be difficult... I remember the Turbo versions work by calculating frames without rendering them, and then drawing only say 4 of 5 or 3 of 5, so perhaps a similar technique could be used on the Amiga.

Also 6 buttons :-)

What about ElfMania? They did an incredible job!. On 1200 we should have somenthing like that with SSF2

Elfmania is very good for an Amiga game, but it's far to have the logic quality and complexity of the CPS games.

Imagine, 1mb of code ! Only games like Ambermoon from Thalion had such big programs. a big amiga game most of the time has a program of 350kb.

Next, the arcade code is doing thing in a way that an amiga is normally not doing.
