Everything works perfectly. Just a hint : on the main menu, i have a black bar under the Turrican II logo and the menu, can you fix this ?

I have the feeling that the music is a little unbalanced in the volume. The loading music and the music playing during the first miniboss encounter sounds louder than the intro music and the normal level music. But I don't claim to have perfect hearing, far from it actually

Nice to see the Amiga player sprite in the PC graphics though, it seems to fit pretty seamlessly.

[jeff b00toNic]

All bugs ironed out.
Excellent job Muzza!

Can I ask how you coded this? Did you have access to the source code or was it all reverse engineered?

Tried on my 1200, really nice and with the cd32 joypad it is a pleasure to play. Well done!

I did notice this. I've made a post about it here.

It is all coded from scratch by playing and observing the original.
The exception is the TFMX music player. I found code for playing TFMX in an Amiga music app which appeared to have been the ASM ripped from the original game and then modified to play through the OS. I undid the modifications and then made additional changes to work with Roondars audio mixer (used for playing sound effects) and to work with my own interrupts etc.

I didn't manage to get it to run yet with modified settings in die .uae file only (without the gui).

I got it working with the following entry in the whdload_db.xml file.
I did not use a .uae file (and if you have created one, delete it for this to work)


I found that setting FAST_COPPER=FALSE means the music plays slowly.
Setting FAST_COPPER=TRUE fixes the music but does introduce graphical bugs in the status bar.


I'll look more into this in the future, and may package up my own A500 mini versions with future releases, if I can work around the emulation bug...

Cool, thanks for the info. I'll try that later
Nice to see you using an A500 mini as well.

[Gzegzolka]

Played latest version and I like it a lot. I like option to choose player sprite and controls configuration.

I've noticed this too.
Perhaps the volume settings aren't the same everywhere?

It still sounds pretty damn good though

[nikosidis]

This is just beautiful!
Played on my A4000 latest version.
I like the DOS player sprites. Thanks.

[Tigerskunk]

Great work. Also nice to see you created a custom engine for that.

And looking forward what you will do with custom art and gameplay in future with this amazing engine. Will be awesome.

Hi, I have just tested it and I find the title screen with the options ingenious, so everyone can choose the character he likes, as a FAN of the VGA version I welcome this step very much. The game is already great, I can't wait for the final version. If you need beta testers or something like that, let me know!
I still have one idea. Could there be an option to set the frequency of the autofire? It's a bit higher on my autofirejoypad, so I would have no reason to play the joystick version, and could do everything with the CD32 pad.

Thank you

I'm confused, if you use a joypad, you just hold down fire - you don't need to use an autofire switch.
Are you saying the player shoots faster when using a joypad with an autofire switch, than it does if you use a CD32 joypad and just hold down fire?

[saimon69]

Hmm makes me think, what happened to the orientable laser beam? (the one that comes when you hold fire in a normal/two buttons setup)?

[jotd]

it's blue or yellow button.

Tried that yesterday, lost a lot of lives at level 1. Exactly like the original

I noticed that the main music was a bit off on my machine. This is because of broken TFMX replay routine which doesn't wait enough when writing to DMACON. You have to insert delays after writing.

In-game music works perfectly.
