Final goal?Write a game for the Amiga 500. Bonus goal would be for the same game to run on the Sega Mega Drive (Genesis), but I'll work that out once the first goal is achieved.
Lets start!I have an Amiga 500, and as mentioned before I'll be following the Amiga Format Bullfrog tutorials for writing a game in assembly language (I'll be writing separate blog posts for each tutorial). OK so tutorial 1 was pretty straight forward, very basic beginnings pretty much incrementing a register to move a sprite position and understanding some basics. I've had a quick flick through ahead of the future tutorials and it's pretty obvious that I'm going to have to do some extra research!
OK after some quick googling, I've come across the following websites:
Through those links I was able to download numerous pdf documents, text file tutorials and lots of other people discussing assembler. Great!
A few people had mentioned particular books that they recommended, which then put me on a mission to hit ebay for real world BOOKS! Ebay books for 68000 processor
|Real world books I've ended up with, should keep me going for a while!|
"Lets get real"OK so coding on the Amiga 500 is great, I have DevPac 2 and I can run simple examples. However, this is going to take forever! Not only is assembly language slow to code (especially when I'm learning), but one of the biggest draw backs is the lack of resources on the machine. As in, I can't just Google something and try it out. My Amiga 500 is on my desk and sits next to my laptop so yes I can Google stuff, but I have no way to transfer files across other than typing out line by line. What do I do?
Ebay to the rescue again... I've purchased an Amiga 1200 (with a broken floppy drive - hopefully I will blog to explain how I will fix it). The great thing about the Amiga 1200 is that you can connect it to the internet, and also use a compact flash card as a hard drive!! 4Gb!! It's still in the post, but I expect I will try and code on the A1200 and once I'm up to speed I'll try and create boot disks with my tests and trials for the A500. Remember my goal is to write a game for the Amiga 500 not Amiga 1200!
I've read through most of 2 68000 books, and I think it's becoming clear that I'm learning vanilla 68k assembly language. I need some Amiga specific references. I'm using DevPac 2, but maybe I need to get my hands of DevPac 3, AsmOne or some other assembler package? And then find a reference + tutorials for that package?
I have stumbled upon Easy68k, this is an Editor, Assembler and Simulator for the 68000 that runs in Windows. Again this looks like just vanilla 68k, but looks like a great way to learn the basics without crashing my Amiga ever time!
Do you still code in Assembler?!
Would love to hear from anyone who still codes in assembler, especially for the Amiga machines. Or maybe if you used to? Any hints or tips you could recommend?
