Turrican 2 MS-DOS AGA conversion
Hi,
I've shared my work in progress conversion of MS-DOS Turrican 2 in the zone. This is basically the same as the Turrican 2 we know and love, but with more colours. This is a project I started initially to learn Amiga ASM, although much of it is written in C in the end. I also wanted to create an AGA game - something I couldn't do in AMOS back in the 90s. It is only the first level, and various features are missing - most notably the bounce weapon does not bounce, there is no mid-level boss and the player cannot die. However most other features are working - even if many require extra polish. It requires Fast RAM to run at 50hz on an A1200. From testing I found it can run at 50hz on a base A1200 but only if I reduce the number of bitplanes. I may do this eventually, but for now I'd rather get it working without modifications to any of the source artwork. Currently it uses 8 bitplanes. I've tested on my real A1200 with Blizzard 1220/4 plus various WinUAE configs, but as this is the first thing I've released on the Amiga in the last two decades there may be unknown compatibility problems. Please let me know if it has problems on your machine. Cheers EDIT: This game has now been released, see the release thread here |
Could you please post it here or on eab ftp? I don't have access to the zone
|
cool i will test it ;)

Hi,
Does the game work without Fast (without VBL of course)? Because I just tried without Fast with WinUae and it always crashes (Quickstart A1200). I have a question regarding the second level part with the ship. On the OCS version, there is a parallax which is not present on the PC version. Do you think you'll add it ? Thank you for your work. |
Now that's a great project @Muzza :)
I have made quick test via winuae, and i can say that all is running almost greatly yet. Prolly the 360 weapon activation need a shorter time pressing the button, and the jumps need a bit of extra work but... for being a first test release is awesome congrats, keep it up the good work |
@Muzza
Just tested, runs great on my stock A1200 with 4mb fast RAM! Impressive work. PS: The game loading after Amiga DOS from floppy shows some garbled graphics, perhaps normal? |
No luck with a 060 - stops at grey screen. :crying
|
Holy shit, the demo is far better than I expected - I'm really impressed. The game feels 100% like Turrican II - some things are still missing, but I didn't expect that - great work so far.
The only thing I found worse so far is the Turrican sprite. It looks better in the amigaverison and is also better animated there. Please keep working on it :) Do you know these tools? https://github.com/movAX13h/turrican2tools |
Running perfect on ACA1233-55.

Wow! incredible work! I've seen the MSDOS T2 before but not played it, and you've done a great job! I love how different everything looks. It's running smoothly on my A1200/030
You've got the handling down perfectly! |
Please, support 2 button joystick such as Amiga original :-)

and small gameplay:

that's is just great. Which assets did you re-use? graphics? code? sfx?
|
Holy f*ck! This is beyond cool indeed!
And once again, the proof that 1200 should have come with 2/4MB Fast out of the box... |
Cool expertiment, but it is not 50 fps, as the original Turrican II on the Amiga was, and the PC version of the main sprite is ugly. The real Turrican sprite is the Amiga one :P

When I bodge it to use fewer bitplanes the RAM requirements go down of course. Quote:

Changing my WinUAE config to use an 060 it ran ok for me. If anyone can point me to a WinUAE 060 setup that does not run, I'll try and find the problem. |

I completely predicted the Turrican sprite would get complaints :), and I've seen several comments about it already! I agree it is worse, I was thinking I would add an option in the menu screen to use the Amiga sprite. They're both 16 colours. And yes those tools were very useful in getting the artwork and extracting map data. I will need to credit the authors in a future version. |
