@TimmSkiller - could you try this test build? https://f.secretalgorithm.com/Bm7Gg/godmode9.firm

ZeroSkill1 commented 3 years ago

Will try it right now.

ZeroSkill1 commented 3 years ago

Seems to work so far, trying to verify contents now.

ZeroSkill1 commented 3 years ago

Verification passed, trying a CIA build next

ZeroSkill1 commented 3 years ago

@d0k3 okay now this is interesting. The CIA built just fine but it only inserted 256 contents instead of all 1094. Maybe this is because a regular ticket can only hold 256 contents in the content index?

ZeroSkill1 commented 3 years ago

If that is the case, then you'd have to implement larger fake tickets to accommodate for more than 256 contents.

luigoalma commented 3 years ago

Current fake tickets should cover 1024 indexes, but CiaStub struct, ticket handling code on cia building or parsing, and a few things cia.c would need to change to support the variably sized tickets, currently only takes ticket common size, that's one thing I did not implement changes to when giving dynamic size ticket support code.

ZeroSkill1 commented 3 years ago

Well I spoke too soon. When I mount that CIA, and try to access any contents inside it, I will get thrown into an exception loop.

ZeroSkill1 commented 3 years ago

It's quite strange, it will crash, but then it will keep on crashing and crashing. Because of that, I had to force shut off my console. There are like 43 exception dumps in my gm9/out folder

d0k3 commented 3 years ago

Some remarks about this 'fix':

So, not so nice. But at least it fails gracefully now in standard mode, and you got a way of building with a special build. And, before I forget it, thanks @luigoalma for additional code.
