WIP fix for Big Mutha Truckers 2 (SLUS-21086)

Code:

--skip freeze at start of gameplay(breaks physics)
eeInsnReplace(0x003d69d8,0x5440ff5b,0x5400ff5b) -- 0x5440ff5b >> bnel v0, zero, $003d6748

No longer freezes, but trailer physics is all messed up. trailer doesn't move correctly, falls through road, truck flips upside down, etc

0x003d6748 is the offset causing the issue

Probably needs an accurate FPU Addsub / Muldiv

Tenchu - Fatal Shadows
SLUS_211.29

Fully working but with some graphical issues I suppose. There's a possibility that the patch is the cause of it.

MTV music generator 2 NTSC

eeObj.WriteMem32(0x00201aac,0x1000fff4) -- 0x1000fff4 >> beq zero, zero, $00201a80

I guess past freeze? I can hear sounds, press buttons, etc ... but interface is frozen :ambivalence:

according to chatgpt this means the command: The safe area is the area of the game screen that is guaranteed to be visible on any TV or monitor. Some games may display important information or UI elements near the edges of the screen, which can be cut off on some displays. Adjusting the safe area ensures that all important information is visible on all displays.

Guitar Hero Van Halen

CLI

Code:

--gs-uprender=none
--gs-upscale=motion

--host-display-mode=16:9
--vu1=jit-sync
--vu1-mpg-cycles=9000
--vif1-instant-xfer=0
--vu1-jr-cache-policy=newprog
--ee-cycle-scalar=2.5

LUA

Code:

-- Guitar Hero Van Halen
-- emu used=kof 2000 v2

local gpr = require("ee-gpr-alias")

apiRequest(0.1)

local eeObj = getEEObject()
local emuObj = getEmuObject()

local patcher = function()
--vu rounding
eeObj.WriteMem32(0x003e9648,0xd3400000)
--freeze skip
--eeObj.WriteMem32(0x00376868,0x100000a6)
--alt freeze skip
eeObj.WriteMem32(0x00376ae0,0x1400fffb)

--emuObj.ThrottleMax()
end

emuObj.AddVsyncHook(patcher)

In game. No graphical issues but needs work.

Note:

These later "full band" guitar hero games have a bypass for the "needs microphone" message that prevents you from playing only with a controller.

Hold PS button, in menu, turn off your controller
Hold L1 and Left on controller, press PS button to turn back on controller
keep holding L1 and left the whole time
after controller popup goes away let go of L1 and left
controller works!

A lot of what was in that ChatGPT txt was PCSX2 related. The PS2 emu on PS4 is quite a bit different, but still very useful info.
