I was really talking about Dune I, but I wouldn't mind a peek at Dune II.

Someone should make a site with all disassemblies available.

I would not call that "source".
It's a bit big, and bear no great interest. It's not commented, and most of it is raw assembly data. Most of them would need rework before reassembling (apart from Battlechess)
The interesting part is the resourced AmigaOS LVOs and sometimes some information about how the protection must be removed.

ok, I've uploaded the whole load here: http://jotd.free.fr/resourced_games/

Thanks JOTD!

It's a shame I have to go working tomorrow or I'd spend all night looking at these.

Well you can take a couple of years off work to understand all that stuff

I started work on a table based disassembler a few months ago, I was planning to use those tables to decompile the code to C and go from there.

As an alternative I could try to translate the code to x86, ARM and go from there. I've seen it done successfully before.

There are a few more cd32 games containing executables files with debug infos:

- Road Kill.
- Bump' N' Burn.
- Nigel Mansell's World Championship.
- Kid Chaos.

I'd be interested in seeing a decompile of K240. I'm certain there are more secrets in that game.

Can these asm files be turned into C source?

Did you ever investigate any of these games?

hitchhikr · 12 November 2009, 19:20

I just checked and seen that they had debug infos, nothing more.

This is not an easy thing to do. In fact, if you could write a program to do it well, you could make a lot of money. So, no.

Hmm. Yes, these are mostly only useful IMO to take a quick look at the source without loading up Resource.

An interesting project would be one where people who disassemble things in Resource get together and share notes and results, including the in-progress or final .rs files and the resulting compilable source code.

Anyone participating would need to be aware this is a timely process. I am still disassembling Pools of Radiance, with multi-year breaks in between sessions. Add to that Dungeon Master, and various demos, intros and so forth.

I don't suppose there is a resource users forum anywhere?

Will do cobber. I'll populate it with some initial content then respond here for feedback before taking it further.

Here we go: amiga reverse engineering wiki.

Anyone care to join in?

Edit: posted a thread on it here.

Cool thread. I thought I was the only one geeky enough to want to disassemble Amiga programs, change and reassemble

. IRA by Frank Wille has been improving and I have submitted bugs which he has been fantastic at fixing but the source is hard to read and only the cpu instructions are supported (no mmu or fpu support and I want to do OS library disassembling too

. So after looking over the ancient ADis sources from Aminet which were easy to read but old, I started making the changes I want. Here's a work in progress...

http://www.heywheel.com/matthey/Amiga/ADis.lha

It's not very well tested but let me know if you find major bugs. Type ADis ? or just ADis in a shell for options. The stack may need to be bumped if disassembling larger files. I'm open to changes or additions you would like to see also.

@copse
Nice job on the Wiki.

hitchhikr · 07 January 2010, 22:51

IRA will be useful when it'll be interactive.
It could be interesting to build an interface around it (with it's own or eventually Resource database handling) in order to a free clone of Resource.

matthey · 08 January 2010, 01:15

@hitchhikr

IRA is defiantly cool and gave me some of the inspiration to start working on ADis. I'm not a very experienced C coder and adding fpu and mmu support to IRA looked impossible. Frank told me he runs a debugger to figure out what to change in IRA. I have been able to do a lot with ADis in a short period of time. ADis has an innovative way to find and follow code. ADis would be a much better candidate for making interactive than IRA imho. It still doesn't have all the features that IRA does but it has some that IRA doesn't. The code is available as with IRA. I included the source in the archive above. I'd love to have someone make it interactive. I probably won't because I want to disassemble and reassemble some programs after I have it good enough for what I want to do. The last big thing I will likely do for awhile is fix the -l (library) option that marks functions, ROMTags and data in libraries. Maybe add support for function names from FD files. I would also like to make ADis so most programs can be disassembled and reassembled with minimal or no changes. It still won't replace Resource but it's nice to have different tools. Did you give ADis a try?

kamelito · 08 January 2010, 22:35

Does anyone remember a french disassembler called Sherlock made by a company named Someware? I tested it for Amiganews I think in 1994, does anyone still have it?
I think it was release in 1994.
