Creating game patches for HDL

Okay I know you guys always say search the forums first and well, I have but I got no positive results, I've searched the net too with no luck.

I'm just wondering, I've got super monkey ball deluxe which doesn't work on hdloader with the latest patch enabled and I'm wanting to attempt to create a patch for it although I'm a little lost.

First of all, how can I discover why it isn't compatible with hdloader? Is there anyway to test it, like debug it as if it's running from hdloader in order to give a clue as to where the problem lies? I've dissassembled it many a time using ps2dis and wandered through the sourcecode aimlessly although I don't have any idea why it doesn't work, could someone please give a real starting point for patching games? someone like crazyc a little advice? I'd be extremely grateful :-pray:

As I say I'm not looking for someone to write a patch for me, just some advice on debugging and such would be extremely helpful :)

Look at ps2 hd website, they have a tutorial about how to make patches for games. The one they show how to fix is Kuon.

yea I've read that before although that only seems to tell you how to fix games with the cdvdman problem (which are probs fixed with hdl now anyways:() and it doesn't tell you why you're patching the cdvdman bit, in other words I wanna be able to find out what's making certain games not work not just know how to patch some games:(

Well i'm not really sure either. I really want to get monkeyball working too, so good luck! And let us know if you do ;)

also, i would find it interesting to have examples on why which patch work.
for example:
the twinsanity patch removes a stack problem between twinsanity and hdl (as far as i understood it).
it would be even more interesting to learn how this was discovered....*g*

wipey, how's the progress? I'm dying to finally play this game.
I never played it, my laser doesn't read DVDs anymore, so it looks like I will never play the game and that would be a goddamn shame.

We're all praying for you to hopefully fix this somehow! :-pray:

lol sorry I haven't even attempted, sure I've dissassembled super monkey ball but and had a look around, but since I haven't a clue what I'm looking for I have no chance in fixing it, shame there's no better tutorials on this sort of thing:(

well, I'm sorry to hear that, but I was also hoping that someone like crazyc as you mentioned in your opening post would maybe read the thread.

I tried a few things too, but I don't know what's wrong.
I read it works on ToxicOS, but is there a chance to get that to work with DMS3?

hum so maybe if we figure out the difference between toxicos and hdloader we could get this thing working?
what exactly is toxicos anyway, is it just a modified version of hdloader, and why does it only run on dms4?
