Re: Spyro Year Of The Dragon USA's Infamous Anti-Piracy Detection Destroyed In 2023 By GameShark Codes Thanks To MottZil

There is no freeze with the PDX USA patch, though. I am looking into the old memory dump I found today. Here is a code snippet from the hook: 8000f0c4 li t0,0x8007af6e 8000f0cc lw t1,0xff6a(t0) // 0x8007aed8 subroutine for regional check of anti-mod routine 8000f0d4 li t2,0x3c03bfc8 8000f0dc bne t1,...

I am not familiar with the NTSC version, but I think the PDX patch does work the same way. The anti-tamper memory scanning is still enabled, though. While the anti-mod routine is bypassed, any memory modification within specific range would trigger final boss crash. I am not sure how many times the ...

Re: Can someone run this Trainer?

By the way, many intros are coded for the newer GPU revision of the PSX: https://psx-spx.consoledev.net/graphicsprocessingunitgpu/#gp0e4h-set-drawing-area-bottom-right-x2y2 They do use the Y-coordinate bits which are unsupported on the older GPU. Moreover, many emulators have got a problem with this...

Re: WORKSHOP CODING INTROS & DEMOS

. Thank you iNC for sharing the knowledge and work! Even though so many years passed when the popularity of PSX was at its peak. I was always under impression of the PARADOX skills (and all BAD, LFC, HLG, MUPS relatives). These LC games look very easy to patch out with emulators nowadays, but I can...

No, no. Tomb Raider hangs, because it does use GetlocP and subchannel Q data to seek the CD Audio tracks precisely.

Re: WORKSHOP CODING INTROS & DEMOS

Thank you for the reply! I am testing the PAL UK version. But I have figured it out eventually. It is the ccpsx -Xo$80020000, which was causing the problem. It does work when the -Xo$80100000 is used instead. I do not understand what it is responsible for though. I have started fiddling with the tra...

Re: WORKSHOP CODING INTROS & DEMOS

Hi! I am interested in writing a small loader to inject my own code before the game starts. It is mostly for the LibCrypt cracks for games that have their code encrypted (Spyro 3) or packed somewhere else (Sydney 2000, Final Fantasy). The problem is I neither do not know how to code nor I want to le...
