Fixing unplayable games

Patch for Petz - Horsez 2 [SLUS 21689] (U)

This patch fixes the hang at first loading screen else the game requires EE cycle rate +2 or +3.

It already works in Sw mode. There is a problem with bars but hopefully that can be fixed soon.

Hello Sir,

I have tried to run it (SEGA AGES 2500 Virtual-On) in software rendering mode. But unfortunately, the performance is pretty awful on my 8th generation i7 laptop, and hardware mode runs in monochrome, which makes it basically unplayable, though frame rate in hardware mode is pretty neat.

I guess the problem might be simply rooted from color space in 3D engine, perhaps RGB 565 is misinterpreted as monochrome 16bit? Not sure, but I hope that can provide some clues into the problem.

Please take a look into it once again, if you have chance and would like to. Thank you very much.

Ok, thank you for testing.  
I looked into missing dialogues during cpu turns. That is also EE cache issue, or game expect really slow DMA/EE. I'm going to test that later, but i don't think i will be able to do anything myself if i will confirm that's also cache issue, and not EE speed itself. 

For now i created patch to skip those dialogues, so game can be played little bit more comfortably. Tested only 2 times, so no idea that its fine to use it for more complicated stages. 

Code:

// Skip xag_stop in XagStop function
patch=1,IOP,000a73f4,word,00000000
// Skip treq_XAG if command is 0x36
patch=1,IOP,000a4560,word,0807fff7
patch=1,IOP,001fffdc,word,24190036
patch=1,IOP,001fffe0,word,14990003
patch=1,IOP,001fffe8,word,0802915a
patch=1,IOP,001ffff0,word,0c028bc2
patch=1,IOP,001ffff8,word,0802915a

// Skip not working dialogues to speed up gameplay
patch=1,EE,E001417A,extended,00183AA4
patch=1,EE,20183AAC,extended,00000000

Hello.
This is the code for Itadaki Street 3, but suddenly the screen got bigger and the game speed more than doubled.
It was about 5 minutes after I started the test.
Certainly, the character's message did not come out, so I am very sorry that there was a problem.

Is there anyone who can fix it? Also, as with the actual PS2, I want to display the character's message and play, so please update PCSX2 as well.

thank you.

A patch for Dance Summit 2001 to allow upscaling + progressive/no interlacing
Serial: SLPM-62029
CRC: 0xF881A604


NOTE: This is no longer required in development builds to get the upscaling to work, but still gets rid of the interlacing (but with some loading screen glitches)
