SquidgeSNES is a SNES emulator created by Squidge.
Contents |
Installation
- Choose a directory on your SD card and unpack the archive directly to it.
- Copy roms into the “roms” directory.
Note that the “skin” and “roms” directory must be present in the same directory as the executable (squidgesnes.gpe)
You can also put your ROMs in “roms\snes” then in the options have 'Use absolute rom dir' unchecked.
Command line usage
If you wish to use the emulator in the command line, you must use the following arguments:
- nrtm - /usr/gp2x/gp2xmenu does not charge while leaving.
- loadrom=<Rom> - <Rom> loads automatically with launching.
Example: squidgesnes.gpe nrtm loadrom=roms/maRom.smc
Hacked Version By Reesy
See the GP32x Forum for more info.
"I've been hacking at Squidges snes emulator, mainly to try and sort out the sound. It took me bloody ages to work out that stereo rendering is broken in the source code. I've not found the exact problem yet, so I have just disabled stereo rendering which gives us a temporary fix.
While I was fixing the sound I also added zipped rom support and also added support for quad frame buffering while in 16bit mode, this is still very much WIP but it works pretty well for the most part. I've also added auto-frame skip, there is no way to current switch this off at the moment as I've not looked at Squidges menu in much detail so I have no idea how to add extra menu options.
I've released 2 versions of the emulator, 1 has squidges original settings and 1 has Yoyo's GP32 hack settings. Again once, when I get to grips with squidges menu system these hack settings will be configurable from the menu but for now you will just have to have to binaries."
To Do
- [improved in 0.38] Sprite priorities
- [done in 0.39] Rewrite sound outputing code
- [done in 0.39] Integrate the SPC700 asm core
- [done in 0.39] add another faster shortcut (L+R+Start) for menu
- [fixed in 0.39] The "Vol Min" or "Vol Max" text comes up in the middle of the screen out of nowhere and annoys people
- [fixed in 0.39] In some games the picture is not center
- [fixed in 0.39] Frameskip seems to be set at auto no matter what you choose.
- [fixed in 0.39] ROMs do not start from command line
- [fixed in 0.39] CPU speed would better be choosable in increments of 5
- Tecmo Super Bowl III: helmets when selecting a team are all red
- [?] Megaman 7: messy after the intro, the graphics become garbled [it's custom chip emulation broken?]
- Equinox: sprite layers slightly wrong. Your character sometimes appears in front of objects when he is really behind them.
- Mario Kart map screen: sprite priority problems
- Gradius 3 US: when you're trying to select a type for your ship, the other types are invisible instead of grayed out until you highlight them.
- Crono Trigger: sometimes after a fight, the sprites gets alot of random sprites around them
- Super Metroid 2nd level, after Cirrus Station: just keep going down the level and you'll eventually hit a section that is completely black
- [fixed in 0.39 but unplayably slow w/gfx corruptions] Yoshi's Island: needs SuperFX emulation, which is now broken
- Super mario RPG: needs SA-1 emulation, which is now broken
- Street Fighter Alpha 2: needs S-DD1 emulation, which is now broken
Controls
Upon startup, a menu will show. The following key sequences are recognized:
- A
- Menu escape - Goes back a menu, returns to game if one is playing or the OS
- B or control stick click
- Menu select - Chooses a menu item
- Up/Down on control stick
- Choose menu item
- Vol+/-
- Volume Control
- Use full screen scaling - Stretches the image of the screen of the SNES to all the screen of GP2x.
- Show FPS - Posts a meter of FPS (Images per seconds) in the top left of the screen.
- Enable vsync - Always waits until the screen is completely full before rafraichir it (reduction of the flickerings).
- FPS to limit - Limit the emulator not to exceed the number of FPS (Images by seondes posted) definite here.
- Frameskip - Number of jumps of the image. A large value indicates a fast emulation but deformed graphics. A low value allows a fluid but slower emulation.
- Audio processor enabled - Activates the emulation of the sound processor of the SNES. It can slow down the emulation thus high value it is not recommended.
- Audio processor transfers - Mutes the sounds generated by the processor of the SNES. Perfect if a game nessesary that the sound processor functions but that you do not want a sound.
- Use Rom absolute to dir - Uses the absolute way "/roms/snes" (where "roms" is located at the root of your SD card) in the place of the relative way "roms" (in the same directory as the executable).
- SNES-type action short props - Rocker enters the buttons A, B, X, Y. With = Y, B = A, X = B, Y = X (the standard lever SNES).
Always remember to save the settings after making adjustments. Settings are saved to the file “ssnes.cfg” in the same directory as the executable.
In-game usage
All keys are mapped directly to the GP2X-equivalent buttons, apart from the action buttons, which are mapped according to the preferences in the settings menu.
To exit back to the menu, hold the ’select’ button down for a few seconds until the menu shows.
A previous version of SquidgeSNES, 0.35 beta, will not play ROMs on some GP2Xes. In some cases this can be fixed by running CloneKeen2X, closing the application, and then try running SquidgeSNES again. It is not yet clear why the issue exists, but on the whole it appears to be fixed in later versions.
Screenshots
Skinning
The menu system used in SquidgeSNES is fully skinnable, check out the “skin” directory in The Archive. The easiest things to change are the icons and the background, although you can change the rest as well. All files should be 24bpp BMP files.
Transparency layer Issue
Arguably, the single most debilitating issue with SquidgeSNES is the transparency layer issue. This is a problem where certain background layers (fog, etc) completely block out all other layers, making the game either unplayable or annoying to play.
The quick fix for this is to press down the entire volume control button on the gp2x, and look at the top right corner of the screen. Continue to hold the button down, and when the background numbers pop up, use the "A", "B", "X" and "Y" buttons to selectively disable or enable background layers.
The advantage is that same games become playable. The disadvantage is, particularly in RPG's, that critical game elements are disabled (like text boxes/bubbles). You can, however, switch between disable/enabling to see the missing elements.
Game Compatibility
Please use the new compatibility pages. The continued use of the lists on individual emulator pages will result in a temporary ban!
Thank you for your cooperation.
SquidgeSNES has a problem with the transparency layer, ignore documenting these issues if they are minor since any game that uses it will have the same issues.

| Megaman X | Works | 0.39 | 255Mhz/11025Hz/Mono/Fs0: ~ 60fps (fullspeed=60) 200Mhz/11025Hz/Mono/Fs0: ~ 50-60fps 200Mhz/44100Hz/Mono/Fs0: ~ 46-60fps |

| Soul Blazer | Mostly Works | 0.37a | Around full speed with good sound, however once you get to the second town, because of the messed up layers, the fog completely covers the screen. The only way to get around this is to mess with the background settings by holding the volume button down and pressing a, making the fog go away. However you're going to have to go back and forth with the background settings because once one of the layers is taken off, many things will be taken off with it which you'll need in order to get around |
