Nes Emulator Question

[MagusZ]

First off I DID SEARCH I couldn't find this problem or answer..

Anyway I am using GPFCE and I can get into the rom select menu but no matter what button I press all I get is a "loading..." screen and then it brings me back to the rom select screen.

I have tried many different roms and installing it many times (basiclly I been uncomprrisng with winrar into my SD card) Any help would be appreciated

Not 100% sure, but I think it has to do with where the roms are on the SD card. I haven't used it in a while so I forget.

GPFCE - NES emulator for the GP2X

This is a gp2x port of the **great** Open Source NES emulator FCE Ultra:
http://fceultra.sourceforge.net. If you enjoyed using this emulator, please
keep in mind that this would not have been possible without the hard work and
dedication of the FCE Ultra developers.

In case you don't know what the NES is about, see:
http://en.wikipedia.org/wiki/Famicom.

My main reasons for working on this port is to get some game programming
experience on smaller devices. Although coding/porting an emu is
generally not the same thing, it's still pretty cool.
I'm an Enterprise Java software developer by trade, so this is a nice side project
for me, and a welcome change of pace. I'm also planning to write some
original games in Java for the GP2x. This should be interesting....


------------------------------------------------------------------
What's new
------------------------------------------------------------------
Current version number is now: 0.2

Many usability features were added, thanks to some great input
from developers and users on the gp32x.de board. Some of the
changes went into the selector frontend.

(I have sent my selector customization changes to kounch,
so hopefully the changes will make it into
version 1.2 or later for other projects to use)

There are now 4 executable scripts.
gpfce
gpfce_showfps
gpfce_swapbuttons
gpfce_showfps_swapbuttons

showfps: this means FPS is displayed on the upper left of the screen
(in non-stretch mode only).

swapbuttons: this means instead of Y/A as NES_B and B/X as NES_A
use A/X as NES_B, and Y/B as NES_A. (think NES MAX)

Volume meter is now shown on the OSD when adjusted.


See version history below for more details.

Depending on feedback, speed and even more compability will
probably be the major focus going forward.


------------------------------------------------------------------
Current Features
------------------------------------------------------------------
- .zip file support
- 22050 Hz Mono Sound support with volume control support
- OSD Volume bar
- Load/Save state (up to 10 slots, pick by holding down R)
- Hardware stretch (See controls)
- Soft Reset
- Savegame support
- 60 FPS without frame skipping on many games
- Configurable Turbo Fire (hold L to toggle)
- Game genie/Cheat code (functionality already exists in FCEU 0.81)
- Sorted display of 2048 roms per subdirectory (recommended 512-1024)?
- Semi-Configurable button layout (startup only)
- configurable FPS display on upper left hand side

--------------------------------------------------------------------
Version History
--------------------------------------------------------------------


ver 0.2 5/29/2006 MD5SUM: dd75fa3f090f9298f9f4afff01ab96f2 *gpfce

- Sound output issue with stereo fixed, now using
22050 khz 16-bit mono. I've tried interpolating to
44khz mono, but the results seemed similar.
- selector supports up to 2048 files, sorted, with
alpha scrolling via left/right in addition to
page up/down via L/R.
- additional startup scripts to select button and fps
configurations
- can load FDS files, but does not seem to work yet
- configurable buttons (use swapbuttons version )
- configurable fps (use showfps version)
- Configurable turbo fire control
- Selectable save slots from 0-9
- Volume bar
- compiled with GCC 4.1.0 -O3 with profiling


ver 0.1 5/23/2006 MD5SUM: 13681f25713ad04c535c23f8c61f1e0b *gpfce


- Initial version
- Around 60 fps with sound
- Load/Save State
- Hardware Stretch
- Soft reset support
- No GUI, using selector with config
- Hard coded 22050 audio, 16-bit, stereo
- compiled with GCC 4.1.0 -O3 with profiling
- Hard coded config path. This is to prevent users
from filling up the gp2x space by accident


------------------------------------------------------------------
Usage
------------------------------------------------------------------
1) Untar the emulator tarball onto some directory on your SD card.
2) You must have a directory called /roms/nes on your SD card.
Put the roms in there, i.e. /mnt/sd/roms/nes is the gp2x path.
Rom files can be zipped.
3) The emulator will create a subdirectory under roms
/roms/nes/fceultra. Save states etc. go here.
4) To start a different rom while running one, hit L+R+JOY.
To exit the file selection menu, press start.
5) For FDS support, put disksys.rom in /mnt/sd/roms/nes/fceultra
Note: FDS roms must not be zipped.
6) For GameGenie support, put gg.rom in /mnt/sd/roms/nes/fceultra

------------------------------------------------------------------
Cheats
------------------------------------------------------------------

gpfce uses the cheat mechanisms already provided by
http://mednafen.com/documentation/cheat.html Note this feature
is untested on gpfce as of version 0.2

To use game genie, place appropraite gg.rom into /mnt/sd/roms/nes/fceultra.
Use -gg on commandline to activate the game genie rom.


------------------------------------------------------------------
Controls
------------------------------------------------------------------

Note: JOY means press in on the joystick (i.e. not up/down/left/right)


In file selector mode
(This is based on selector version 1.1)
----------------------------------------------
Start - EXIT file selector, back to main menu.
B,A,X,Y, JOY - start rom
L - page up
R - page down
UP - scroll up one, wraps if at top
DOWN - scroll down one, wraps if at bottom
LEFT - jump up list by first letter of rom name
RIGHT - jump down list by first letter of rom name




In game
------------------------
Y - NES B
A - NES B
B - NES A
X - NES A
SELECT - NES SELECT
START - NES START
VOL +/- - Vol control.

hold L - toggles between
No Turbo Fire,
Upper row of buttons turbo fire
Lower row of buttons turbo fire

hold R - cycles through save state slots

L & JOY - Save state
R & JOY - Load State
SEL & JOY - Stretch screen toggle
L & R - Reset NES

L + R + JOY - Exit back to menu


FDS only
-------------------------------
L - insert disk
R - eject disk
JOY - select disk



------------------------------------------------------------------
Known issues
------------------------------------------------------------------
1) Stretch mode could use a better aspect ratio. Looks a bit odd.
Might look into some fancy non-2x filtering algorthms, if there are such things.
2) Not thoroughly QA'd
3) S-Video not working
4) FDS does not seem to be working
5) Some compatibility issues
6) Can't sustain 60fps on some games
7) Some clipping issues in some games
8) Game genie behaves a bit odd, although code works...

------------------------------------------------------------------
Might have time to do list
------------------------------------------------------------------
1) Fix more known issues
2) Better looking stretch?
3) File based Game genie support
4) Cleaner build
5) Full speed on all games. (This may require some work)
6) Better compability
7) Multiplayer support via cable - this one is obviously pretty
tricky. Will need cables and a usb hub first.
It's definitely possible, but is not a priority at this point.

Read the readme please!

This emulator and I will have babies..GreeNES they shall be

 

[MagusZ]

I DID read the read me, and I did make a folder in my SD card and put my nes roms in the folder within.

I don't know what "untar" means I assumed he just meant uncompress intot he SD card which I did. And my roms are in /roms/nes.

Where he says "/mnt/sd/roms/nes" Im not sure what "/mnt" is?

But anyway I DID read the read me, If I didn't I wouldn't ask, and as far as I know I did everything it said to do. If I didn't I would appreciate it if you point it out what I missed not just paste the read me. I got many emulators working not out of dum luck but because I read the read me.

If it has any capitol letters it will not work.

Check to see if that fceultra directory got created, that is a sure sign that it has found your directory.

Make sure no caps got into your directory naming structure.

The GP2X sees "/roms/nes" from the root as "/mnt/sd/roms/nes", as long as there is a directory called roms, with a directory called nes inside it that is correct.

 

[MagusZ]

^ Yes the fceultra did get created. So my directory goes "\roms\nes\fceultra" no capitol letter everything was done right (as far as i know)

So yeah that folder was created, like I said I can get into the rom select screen just wont load the rom, it just kicks me out to the rom selct screen again. I have tried both unzipped and zipped roms but neither work.

 

[Nekki]

Being as it sounds like everything else is set up properly, maybe you've just got duff roms? Have you been able to use the roms with any other NES emulator?

 

[trooper]

Are your roms compressed (eg, Zipped) or uncompressed (eg,*.nes) ?, If so, Try the opposite to what you have already tried.

Mine is set up with \roms\nes, and that's where all my roms are. The actual emulator is in a completely seperate folder called \fceultra. It works fine like that for me. So I think your problem might be the fceultra folder: move all roms (and the emulator if you want) back one directory so it goes \roms\nes and you should be good to go.

Although it is strange that it finds them and makes a list of them but then they dont work....

Do you mean any other emulators on the GP2x or in general because they work fine on my Pc in FCeultra.

Like I said in my other post I have tried both .zip and .nes, same thing happens.

Mine is setup the way you have it described there. I have a seperate folder for roms and my emulator is in a seperate folder as well. The fceultra you see there is the one the emulator created to save states and such...


EDIT: I got it to work it was duff roms, I guess. They work find on my PC and in my DS/GBA don't know why they wouldn't work here. I tried "new" roms and they work fine now, I still don't understand why my "old" roms don't work in the emu but these do ?
