Turrican 2 MS-DOS AGA conversion

[Stevo2k]

How about some kind of copper trick for the parallax that some games use for some kind of mountain range, mixels creeping me out uses these tricks, I know it uses scorpion engine and i do appreciate how difficult this could be....ideas ideas!!!

Played through the whole lot, all levels & Bosses. All I can say this is an amazing update... Using the original sprite from original Amiga game is the best.

Uploading a video as I type... standbye

No way!! excellent. I suck at that game, never could go past start of level 2, but I think I'm going to play the remake on my A1200

All available stages, all bosses.

Hello,

There seems to be a graphical issue with the "Power Line" weapon ( Pic 1 ).

PAL and NTSC.

Quickstart A1200 + 4Mb Fast.

Could you make audio CD playback instead of TFMX modules? That would allow Turrican anthology soundtrack owners having best gaming music experience.

brilliant piece of work! I can't imaging how many hours were spent remaking it 100%

Is the DOS version better/same or did Muzza create the best version of all platforms?

- is the DOS music the same or horrible beeps/soundblaster FM shit? => music seems 100% module and awesome
- does DOS version have fake copper rainbows? => rainbows are there all right
- does DOS version have overscan? => yes
- does DOS version have ugly hammerhead character? => yes

for the 4th point above Amiga version is better !

Also CD playback could be done, using cd32load on a CD32

AGA for the music too We need more AGA conversions using MS-DOS superior colored backgrounds when they exist (and when the recoloring worked, like here, because there are 256 color versions of games that were criticized like Chaos Engine...)

i know this is a very unpopular opinion, but i like the MS-DOS sprite. can we have an option to choose which one we want to have in-game?

Chaos Engine AGA use 128 colors.

I've no words! That's just fantastic!

This is fantastic and plays really well. It did freeze up on me however after I killed that tripod monster that turns left and right. It was supposed to load the next level but nothing happened although the music kept playing.

Edit : just downloaded the latest WIP 5 and it froze even earlier on

Seconded. This should be implemented as an optional choice in order to satisfy everyone.



While I obviously prefer the original sprite, I don't think it fits well with the aesthetics of the MS-DOS version updated graphics, so I'll prefer to play this also with the updated sprite.

[dlfrsilver]

The speed is excellent. It shows that 256 colors and 50fps can be done on A1200.

However I have triggered a terrible bug in the level where the background playfield is red. I went down and right to a place where a bonus block was, and my A1200 did a terrible sound noise and froze.

[jotd]

I suggest you use whdload versions. If there's issues it's not likely to freeze the machine (even if it's still possible) but will return to the OS with a whdload error, which may even be exploitable by the programmer.

I used the whdload version. My A1200 froze with the music doing creeping sound (like if paula was dying) and the keyboard was locked.

The freeze i got is the one above in video "Turrican AGA freeze 2".

Indeed those videos I posted were using the Whdload version.

Thanks for reporting this. I'm pretty sure I know what it is. I mentioned before I was suspicious of looping sound effects. One video has the screen-wipe sound effect playing, one is the lightning weapon sound effect. These are 2 of only 3 looping sound effects in the game.


I think I have a race condition between the C code that starts/stops the looping sound effects, and the ASM interrupt code that processes when to loop it. I made a possible fix for the last build but clearly it did not work. The difficult part is that with race conditions sometimes you can test for hours and not get it to happen once, then another time it happens immediately. I'll work some more on it.

This was always my plan, but I wanted to try it before having to implement a menu screen.

I considered having it changeable at any time with a key-press, but that would require more CHIP RAM as the players sprites are some of the largest. Ideally I'd keep CHIP RAM requirements as low as possible for the WHDLoad versions. So it is probably safest to have the player choose an option before the game starts.

Also, interestingly, the two versions do not match up perfectly. The gun barrel positions move on some frames (meaning your shots will come from a slightly different location), and frames like the Duck poses are a different sizes.
