Thanks for the info.

I can create an adf disk image with a startup sequence no problem. It's just getting the finished game program file to put in it and point to, but as I say I've no idea how to do it from Notepad with VASM. Exporting a binary file would probably do the trick I think, but as I ...

Hi everyone,

I thought I'd pop back here as I've been giving some assembly projects a go again, but I've hit a bump in the road.

I've been using Notepad++ and VASM to do some Amiga stuff, but it dawned on me that I have no clue how to get a finished output file so I can put it on to an adf disk ...

Just a follow up:

Yep it seems to be working now, and it was the jump back address and the bit check. I was setting the jump back address to &4040, but just leaving it at &C040 and setting only the base address to &40 works.

Cheers Keith!

I've been messing around with Bank Switching using the Gate Array (just for practise, not in this current code), so that makes a lot of sense now that you say it, given the &4000 range.

I'm not using the Firmware at all now except to change the border colour and set the palette on ...

Hi,

Thought I'd jump back on here as I have a specific question regarding the screen plotting code from the Lesson 6 video (Lookup tables).

My question is, do the screen bases in that code just tell the program where to draw the graphics? Or does it actually set the visible screen?

I'm asking ...

Awesome, that's just what I was looking for!

Cheers!

Apologies for what must seem like a really thick question Keith, but I'm getting rid of the last bit of firmware use by incorporating your Key Scanning/Reading code into my program, but I'm a little stuck on how to actually check for a key press.

Like, how do you actually tell the computer if you ...

Excellent! I'll have a look at that Stack trick.

I've pretty much resigned myself to the fact that the game is going to be slow, but as long as it's comparable to the original Amstrad Final Fight conversion in terms of speed then I'll be happy, and any little tricks to boost speed will be great ...

This is great! It works beautifully. Thank you.

I had made some ham-fisted attempt at another transparency method, but I wasn't really getting anywhere.

Would this work with a flipped image? I only ask because I'm literally just about to try and attempt a sprite flipping routine, so may as well ...

Thank Keith.

I tried setting the background colour to black, and it was definitely an improvement, but it's a bit too blocky for my eyes. I'll look in to another way of removing the transparency. I've not used LUTs much, so maybe this will be a good exercise.
