PS4 [Research]PS2 emulator configuration on PS4

No issues. Work great Japanese only.

Game crashes at English patch.
Code: 
-- 0 - japanese
-- 1 - english
-- 3 - French
-- 4 - Italian
-- 5 - German
-- 6 - Spanish

eeObj.WriteMem32(0x20657C1C,0x0)
Click to expand...

Code: 
--ported to PS4

apiRequest(0.7)

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

--eeInsnReplace(0x20657C1C, 0x00000000, 0x00000001)


local patcher = function()
eeObj.WriteMem8(0x20657C1C,0x01)

--emuObj.ThrottleMax()
end

emuObj.AddVsyncHook(patcher)
This works but crashes at main menu. Text was in English

how would one go about finding correct opcode?
Code: 
local code_check1 = eeObj.ReadMem8(0x657C1C)
if code_check1 == 0x00 then
eeObj.WriteMem8(0x20657C1C,0x01)
end

This also changes language to english but crashes at menu...

I think i found out what the problem might be, try replacing 20657C1C with 1 or 0
https://forums.pcsx2.net/Thread-How-PNACH-files-work-2-0


0 means it will write to one byte only.
1 means it will write to two bytes.
2 means it will write to four bytes.

You're trying to write one byte, so try 0

Code: 
apiRequest(0.1)
eeInsnReplace(0x00657C1C, 0x0, 0x1)

unfortunately, still no effect..

@Stayhye You can go to 0x20657C1C in PCSX2 debugger and take that value as the second parameter (the one that's currently 0x00000000).

how is this done? I don't know how to use PCSX2 debugger effectively

Open PCSX2 debugger, press ctrl + g, type in 00657c1c. Pressing tab will show the bytes at that location in the instruction view. Otherwise, you can select the memory view at the bottom left and do the same ctrl + g shortcut to go to that address.

it shows nop (0x00000000) . Also shows this value in ps2dis

*edit - trying to cheat by patching ISO is also a no go. Crashes in the same place, but text is in english

Try this one
Code: 
apiRequest(0.1)

local eeObj = getEEObject()
local emuObj = getEmuObject()
local patcher = function()
eeObj.WriteMem32(0x657C1C,0x1)
end

emuObj.AddVsyncHook(patcher)
Click to expand...

This version also changed the language, but crashed at main menu

Maybe one of these will help, no ?
Code: 
--vif1-ignore-cmd-ints=1
--vif-ignore-invalid-cmd=1
Click to expand...

no luck there either

*edit - best i can do for now

Code: 
-- Metal Slug (Japan)
-- Widescreen hack by nemesis2000
-- ported to PS4 Lua by Stayhye
-- emu used=jakx v2

apiRequest(0.1)

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

local patcher = function()
--english, but crashes emu on PS4
--eeObj.WriteMem8(0x657C1C,0x01)

Enable English patch (L1 + R3) after main menu loads. Works fine like this lol

Hey guys, I'm a newbie. What application are you guys using to convert PS2 isos to FPKG files? Asking because I'm not sure how to configure the CLI and LUA files to get some of my games working properly. Thanks.
