Anyway, you've been releasing forum posts all month... surely that must count for something

I never said I'd ACTUALLY release something this month, let alone the whole thing

It was a joke. Just make it good and we'll all (hopefully) be happy

Yeah. I don't wanna be a noob anymore.

Just 20 more posts and I'll be a junior

Just as a note, your sig has a typo: binary (as opposed to unary, tertiary or deciary) cannot be plural: there are not multiple binaries unless you are referring to compiled code as a "binary" in unix style -- in which case, the quote doesn't make sense.

The actual quote is: "There are 10 kinds of people in the world: those who understand binary, and those who don't."

(and 2 more posts until I hit 500 )

Now I think this is a bug but could just be something I don't know about:

First, the program is great, I'm enjoying it greatly, playing many old games, thanks greatly for it!
I'm running RC7c on a Tungsten TX,
I have DBcache Tool installed and turned on to Auto Clear (I heard it could give problems, but it never did for me, and I couldnt find out how to clear up with it without Auto Clear)
and I turn on UDMH if I want to run SNES (GB and NES work fine without it).
No other hacks are installed that I know of.

This way SNES games work fine usually, and I could even reach about 100% normal speed if I tried, with Chrono Trigger

Now the problem is, that some fan translated (hacked) ROMs dont work, namely the Final Fantasy IV and V fan translations... both the original japanese versions, and the american FFII works (which rly is FFIV US version), also, all versions run fine on ZSNES.

The FFVI fan translation also works perfectly on LJP so its not that its specially against hacked roms, but the ones that dont work are all hacked.

Basicly these 2 games give me a black screen with nothing moving, without any sound, with FFV some grey flickering can be seen, and also if I try to bring up the menu it reacts rly slow as if it was working hard.

So I want to ask if there could be any way to help this, like could updating to RC8 help? I will try to experiment around with different versions of the translations, if they work, but so far thats it.

Edit: If I switch to the C core it still doesnt work, but the grey flicker disappears and the menu is not slow (but still all black and no sound and no reaction from the actual game)
Edit again: actually I cannot reproduce that with any settings now, only black screen, don't know what caused that. Anyway, the games still dont work :S

Did you mess around with Transparency and The Fast Sprites?
Did they work with RC2 or any other releases?
Mess Around with everything in the preferences panel, and try everything with both cores. (C and ASM)
My snes runs great

[kiscsirke]

Yes I did and it didn't work.
This is the first version I've installed (I've only found LJP around 3 weeks ago). If all else fails I might try other versions but I'd rather not, I don't like installing and removind too often.
I did try mess around some, but no effect so far.
And as I said all 'official' games work good so far for me too (US version of FFIV and FFVI, Chrono Trigger and even the japanese FFV), And I just found something that might be related to that:

For the FFIV fan translation (that doesnt work), in 'sys infos' in the ingame emulator menu it says at Type: '[00E3]HiROM,Corrupt/+CoPro#12'
and for the FFV, Type is: '[0002]LoROM,Corrupt/ROM'

for comparison the FFV japanese version says '[0021]HiROM,16Mbits/ROM'

(and at the ROM point in sys infos all my SNES games say '[bad checksum]')

So at Type only the not working ones say 'corrupt', so my guess is that LJP finds these ROMs corrupt for some reason. Which is strange, bcuz as I said ZSNES plays them without a problem. So anyone who knows how this works could tell me if I'm right (in saying that they dont work 'cause it thinks they are corrupt) and why this could be? And maybe how could I solve it?

[Tinnus]

It just says they are corrupted because the files are altered from the originals so the checks don't... check. It doesn't affect the emulator outcome whatsoever though.

[kiscsirke]

But the FFVI fan translation is 'altered' too but it doesn't say 'corrupt' and it works, thats why I think there's a connection . What should they check to, anyway, is there and integrated checksum in the ROMs, and for FFVI the translators changed that too? If the question is not too hard to answer.

[Tinnus]

Yes, I think the SNES ROMs have a CRC or something stored in their header, and I guess the translator used in that particular case fixed it. I do NOT think, though, that the emulator itself makes any distinction in behavior if the ROM is considered corrupt.

[sincloud]

I have a small question~~

My palm is Treo680
I played NES game (Fire Emblem Gaiden) long time
When I used LJP rc3 it works very good but sometime my treo would be reset
But when I used rc7 or rc8
Treo didn't reset any more
But I can not load game after I run LJP from launcher
Load game by quick load is no problem
But can not load it when I used the "load" in game.. (poor English...do you understand? -_-#)

I want to know how to solve the problem
Thax very much~~

[metaview]

const char *CMemory::Size ()
{
static char tmp [20];

if (ROMSize < 7 || ROMSize - 7 > 23)
return ("Corrupt");
sprintf (tmp, "%dMbits", 1 << (ROMSize - 7));
return (tmp);
}

So it seems, it is the ROMSize which has the wrong value. But ROMSize isn't used anywhere else. It means, ROMSize isn#t the problem, but something else which is different in this ROM. But ZNES is too different to understand what might be wrong. Sorry.

Two things I can think of:
1) the ROM was corrupted when you copied it to your SD card; the original copy on your PC is fine. Might want to back up your SD card and reformat it, as the FAT system might be corrupted on it.
2) the ROM is interleaved and the old version of SNES9x used in LJP isn't handling that format correctly (unlikely, but possible). Get a copy of NSRT and use it to check your ROM. It might be able to fix the problem.

[kiscsirke]

First to _Em:

1) that seems ulikely, because since when I first installed this FFV (that doesn't work) I've installed many other files (documents and programs) without problem, and reinstalled these roms several times for different reasons (and at some time, there were 2 copies of FFV on) so I dont think thats the case, I might try it tomorrow though if I have time.
2) NSRT says its not interleaved

To Henk: well, it works on Snes9x too, so there you go. Also, when checking in NSRT, for FFIV and V it says they are a 'possible overdump' and for FFVI it doesnt (and the file size of FFVI changed too when applying the patch, so I guess they fixed the indicated size somewhere), soooo do you know of any way to change the size for the other two too? (Because even though you say its not supposed to be a problem I do programming myself (in other areas) and sometimes something that is not supposed to be a problem is really, because of compiler errors, whatever, its safer to try) I'll do a search on it tomorrow, but now I go to bed (its laaaate) and if you know a solution, its easier.

Also, 2 little observations that might help to find out the problem
1) Even though NSRT says they are not interleaved, sometimes when launching FFV on LJP it says "Deinterleaved mofe 2" (I guess that it being 'mofe' not 'mode' is a typo) for some reason.
2) For the FF5j I tried the Snes9x current version saves in LJP, and they work, so I made some saves for FF5 and 4 too, and tried those too, and at both cases, I can see the screen I'm supposed to see for a moment (I guess a screensave is saved in the save state right?) and then all cinds of colorful boxes/image fragments(but not in the right coloring) start to show up for some time leading to either a crash, or falling back to the blank black screen after a time. Also, the music plays for 1 or 2 seconds seemingly correctly then strange noises come too... :S

[kiscsirke]

well, the problem doesnt matter anymore, as my Palm was stolen today, and I dont know when/if I will get a new one, so d**n. I any of you would be curious (which I dont think you will, but whatever) I can mail these 2 roms if an email adress is given.

Hello, I'm new there, but I played for a long time with LJP 1.0 RC2.
I'm using a Tungsten T5 & it really was stable (sometime slow), mainly using SNES & GEN roms (+UDMH giving 54,450K free ram).

I was curious about evolution of that so great emulator (thanks a lot !) & I installed the new LJP RC 8. Install was OK but, when I tried to launch a snes rom, LJP tells me that the SNES ZEM file has a wrong version number. the version wanted is 0400/0100.

I did installation with a SD-card, my hot-sync cable is broken. but I think it was correctly done.

I will try older version like RC 7 & RC 3 (later, it takes lot of time) & tell here some reports.

You didn't update the .zem files, or not on the correct volume. The Tungsten T5 has an internal volume. Please check this for remains of older LJP.

[amistas]

Thanks for replying me.

I think I totally erased all LJP folders on my T5, including the .zem files. I got one folder in internal memory and another in the SD-card (where the Roms & save files were installed). I erased the two of them. I just made a back-up of the Roms & save folders, on my PC.

After that, I installed the new LJP RC8, with the ZEM files in the binaries, from the "launcher" folder of the SD-card.
The first launch of the LJP.PRC created the LJP-folders in the internal memory, but again, it created the same folders on the SD-card after a manual PDA reset. I really don't know why, but it worked before with the RC2.

The zem files from the RC8 binaries were installed on the two LJP folders created. So, I'm actually sure that no older zem files were present.

Now, I don't have time to install RC8 again (got high school test to study), but I will do it later & tell here the report.

Thanks again for this so great emulator soft (when I'll have some spared money, u will get a donation ).

[flyinghippo]

I know I have made a topic about this, but I figured it would have made more sense to post it here.

Model: Treo 755p
Releases: R7, upgraded to R8
Media: 512MB MiniSD Card
Tweaks: 416Mhz Clock, 208mhz everything else when playing SNES, default 104mhz for everything else.
Module: Everything BUT SNES. (I haven't played VCS or Genesis ROMs, however.)

SRAMs are written at their correct size, but I can't tell if they're written correctly. I can't load any of my saved games. I have done this with and without the use of save-states, and none of that affects it. Any assistance, or other people with this problem (I've seen one report) would be appreciated.

[_Em]

Just out of curiosity, are you running LJP off of your SD card?

[metaview]

Maybe, the access to the SD-card doesn't work properly when overclocked? Did you try it with standard clock?
