Ppsspp: kr0.pgf is unimplemented on PPSSPP

[Panderner]

Some games uses PGF/sceFont i've mentioned in #2788 but kr0.pgf is used for korean fonts are unimplemented on PPSSPP and it's replaced by blank spaces even i used a real PSP font.

LocoRoco 2

BlazBlue: Continuum Shift II

[Panderner]

Although The UI, Memory Stick Warning Messages and Save/Load Screens are ok

[unknownbrackets]

Well, I think it is "implemented":
https://github.com/hrydgard/ppsspp/blob/3ec54d3804fca6314429da3a0cacfa9583a3f680/Core/HLE/sceFont.cpp#L116

It might be a separate problem with PGF support, such as picking the wrong font in the OptimalFont call. I don't know that this is atlas related.

[Panderner]

Korean fonts in menus are ok. but the PGF used in some games are missing.

[hrydgard]

Yeah in the menus we are using fonts of the system the emulator is running on.

Can't really do that in-game as the PGF font system is so different.

[Panderner]

Gran Turismo also affected this issue:

@Panderner

Can you test on EXIT(Pure Korea ver.)?
If you can do it then please upload the screenshot.

[Panderner]

@Panderner

@nassau-tk The Korean version of EXIT (ULKS46054) is entirely japanese like Korean Copy of Monster Hunter Portable (UCKS45036) which is entirely english.

[nassau-tk]

Really?!

OK. I understood it.

[nassau-tk]

@Panderner

If you can try this kr0.pgf then download and test it.

[nassau-tk]

@Panderner
And, I don't have a information about korean PSP games.
So,Please tell me.
Is these games language patched?
Or pure korean language package?

These are games that uses PGF. like Locoroco2, Blazblue Continuum Shift II and Gran Turismo

@nassau-tk That kr0.pgf file that cause issues that Locoroco 2 Crashed for me and some issues for LocoRoco Midnight Carnival:
The letters are too small compared to PPSSPP font and real PSP font:

and here's a warning screen that does not render correctly:

[Panderner]

Here's a crash message for LocoRoco 2 using @nassau-tk's kr0.pgf:

[Panderner]

but using save state to get past loading save crash but some missing letters in the screenshot:

[nassau-tk]

@Panderner
Character size is not tuned.
It's "just test version".

[nassau-tk]

@hrydgard
I have a question about "State Save of PPSSPP". (It's Not Means Save System of The Game.)
If we used "PPSSPP State Save" then it's not change the font file on my knowledge.
The font file is memoried at making save state.
(Will state save data inclued font data?)

1. "Font-A1" installed.
2. Start the game and get state save.
3. Finish the game.
4. "Font-A1" change to "Font-A2"
5. Boot the game and load the state save.
6. It's not change the font. It will appear the "Font-A1".

Is that right?

[hrydgard]

PGF::DoState appears to save all the loaded glyph state so yes, it should appear as Font-A1 I think. This is probably not the most well tested scenario we have :)

[nassau-tk]

@hrydgard

Thanks!!
I understood it.

[nassau-tk]

I tested to check the Real PSP's kr0.pgf header by pgftool.

Result.
"Can't read it."
jpn0.pgf / ltn1.pgf~ltn15.pgf is OK.(It can read header.)
But,It's no responsed on pgftool only "kr0.pgf" .
I don't know why.:tired_face:

[nassau-tk]

@Panderner
Hi!!
Comming "Time of Test "!!
Can you?

I have begun to consider a possibility of "the problem of a PGF file" by the other day's test.
Point is 2 things.These point was move my making mind.

1. A few Hnagul appeared on my test file .
2. Real PSP's kr0.pgf couldn't dump.(not appear error code. just through.)

https://drive.google.com/file/d/1X31Eea5_LTEkoPxBmjZfGGis1Z-ZScSn/view?usp=sharing

I don't know about "Hangul".
So everything is made by "only my sense".
If appear the Hangul then it's good.
But I think it can't be adjusted small.

If you have interest then let's try it and please give me report.:construction_worker:

[nassau-tk]

@hrydgard

If appeared the Hnagul characters by this pgf file then we need rethink about the issue tag change or add "PGF / Scefont" don't you?

Of course,If Hangul "appear".:grin:

@nassau-tk that font can cause issues for LocoRoco and Gran Turismo:

Korean text in Gran Turismo is spammed by same letters:

and here's LocoRoco 2 and LocoRoco Midnight Carnival the all letters stretched horizontally and warning screen still not aligned correctly:

[nassau-tk]

@Panderner

https://github.com/hrydgard/ppsspp/issues/13458#issuecomment-703628746
GranTurismo is needs turn off "Lazy texture caching (speedup)" option.
Maybe you turn on the option's check box aren't you?
Please Check & ReTest it.

LocoLoco...um...
It seems shrinking about half size(horizonal).
It has possible to fix.(Maybe)

How about BlazBlue?
Not good?

[nassau-tk]

@hrydgard
These result means that the issue was happened by "PGF files" I think.
How do you think about this?

This is an amature's idea (Delusion) below.:smile:
For example.

• Real PSP's kr0.pgf has locked or encryption. (Only This pgf?)
• And,PPSSPP has not key of decrypt.

[hrydgard]

I am just thoroughly confused here :) Really no idea what's going on with kr0.pgf.

There might be bugs in our implementation of sceFont, too...

[nassau-tk]

:laughing:

I feel that most strange point is "Can't see header only kr0.pgf by pgftool's dump".
But,other pgf files has no major problem now.

So,We should think light.
Like this.
"If we fixed about kr0.pgf then we will free from all about pgf issue! "(Imprudent?:sunglasses:)

Well,I will think how to way this issue solved.

[nassau-tk]

@hrydgard

There might be bugs in our implementation of sceFont, too...

I think that's "Right".
See,below link.
https://github.com/hrydgard/ppsspp/issues/11055
This issue will happening when loading plural PGF files I think.
It should loaded "jpn0.pgf & ltn15.pgf".
But "ltn15.pgf" is not load.

Well,I will try some font making.

P.S:Please rethink about tag about this issue.

I've tried turned off lazy cache texturing and it worked

[Panderner]

How about BlazBlue?

@nassau-tk Blazblue is ok enough

[Panderner]

• Real PSP's kr0.pgf has locked or encryption. (Only This pgf?)

can we wait for the decryption of real PSP's kr0.pgf?

@Panderner
This idea is my example.:smile:
A true reason isn't understood yet.
We have no choice.
We can only "Just wait" now.

And, I will try modify the "kr0.pgf ".
Please,wait for time.

[nassau-tk]

@Panderner

It's time of test!!
https://drive.google.com/file/d/1X31Eea5_LTEkoPxBmjZfGGis1Z-ZScSn/view?usp=sharing

BLAZBLUE/LocoLoco2/GranTurismo Please test it!

By the way.
When you found the korean text glitch?

[Panderner]

BLAZBLUE/LocoLoco2/GranTurismo Please test it!

By the way.
When you found the korean text glitch?

is the gap for warning screen in LocoRoco: Midnight Carnival is correct?

Real PSP Font:

Current kr0.pgf:

PPSSPP font:

[nassau-tk]

Which is My latest kr0.pgf???
Current kr0.pgf?
PPSSPP font?

And, Check more Korean & English text!!
Try hard!!:kissing_heart:

[Panderner]

Which is My latest kr0.pgf???
Current kr0.pgf?
PPSSPP font?

which is the gap of warning screen of LocoRoco: Midnight Carnival warning screen is correct compared to real PSP font?

[nassau-tk]

And,The gap every character and the margin are never match.
Because,The base Font is different one with "Real PSP Font".
Please think it's OK when it can be seen roughly.

[Panderner]

yep it's ok

[nassau-tk]

OK!
Other games are no problem?
BLAZBLUE , GranTurismo too.

And,LocoLoco2's Save Screen.(not Shrink?)

[nassau-tk]

@hrydgard
We can't check Korean words.
So,We have no choice but to entrust a judgement to @Panderner .
If become no problem (@Panderner 's judgement=OK) my kr0.pgf then are you merge this?
Of course,The problem that a "Real PSP'S PGF file" can't be read is left.

[Panderner]

oops i accidentally pressed close button

[Panderner]

Locoroco 2 level description is fine though

[nassau-tk]

Maybe LocoRoco 2 OK!!
Please Retest "BLAZBLUE & GranTurismo" when your free time.

[Panderner]

I've Gran Turismo and Blazblue it works correctly:

[nassau-tk]

@Panderner
OK!!
Thank you for your testing.

[nassau-tk]

@hrydgard

Well,What should we do?

Note : I will sleep tonight.Good night!

[hrydgard]

We shall merge your new kr0 font :)

[nassau-tk]

@hrydgard
Morning came in Japan!!
And, Thank you for merging it!!

Well,My Font Working is finished roughlly isn't it?

[Panderner]

The @nassau-tk's latest kr0.pgf is merged but please do not close this issue until the real PSP's kr0.pgf is fixed.

[nassau-tk]

Yes, Right!

[nassau-tk]

@hrydgard
I propose for you that this issue should be "PGF / sceFont" tag.
How do you think about it?

[hrydgard]

That's right! I changed the tag.

[Panderner]

This is the real PSP's kr0.pgf
