I Love my GP32, but it's a Blu+ so my question is, will the line problem ever have a work-around, say through a firmware update, or should I give up and look for a FLU?

You wouldn't be happy with the screen on a FLU after having a BLU as it is much better. Most everything has been fixed anyway except SNES but that is too slow to play with sound anyway.

Problem? What problem. Very few programs still have the incompatability errors.

Seems like a lot of the stuff I've tried is not working...Maybe I should start a website devoted to Blu+ certified progs...

Yeah, but not complete. Only for the stuff where I know it.

But... I've got a BLU+ myself, and have only four non-working games... Pinball Dreams (sound crackly), OpenSNES9x, Gianas Return and Numo.
The rest is fine. OpenSNES9x will be fixed, Numo should also be fixed, Gianas Return sadfully will never be fixed.

Is LittleJohn playable on Blu+? If it is I might be tempted to upgrade... (FLU owner)

Yeah I have .04 (i think it's 04) on mine, works great!

snes unplayable with sound, Dave?

I play mine at 160 mhz and have not found a game yet that is not playable with sound and a 3 frame skip....

very funny. frameskip 3 means "absolutely unplayable". unless you want to get eye-cancer.

My BLU+ FAQ:

The GP32 comes in 4 flavours: NLU (non-light unit), FLU (front-light unit), BLU (back-light unit) and BLU+ (back-light unit, Taiwanese screen).

NLUs were manufactured first. They (and FLUs) may require the user to register the GP online before non-commercial software can be used. Note that homebrewed and BLU firmware is available to update the launchers, so a NLU or FLU can run a BLU launcher.

FLUs have an issue with dust getting behind the screen. There are fixes. The front light washes out colours to some extent (this is common with front lights) but quality is still very good. The front light can be de-activated with a switch on the back of the GP.

BLUs have an updated launcher that does not require registration to play non-commercial games. The back light makes colours very vivid, giving the BLU and BLU+ the best quality screen by far.
The BLU and BLU+ can both have their backlights de-activated by holding down the select button for a couple of seconds. In rare situations this can affect gameplay, though any problems can usually be circumvented by mapping to another button.
When the backlights are turned off they are playable but require a lot of local light and have a narrow viewing angle. When the backlight is on and the GP is used in an area of high light (typically outside on a sunny day) viewing is difficult. Turning off the light improves viewability, but some twiddling of viewing angle is needed. The NLU is far better in highly lit areas.

In late 2004 GamePark sourced their screens from a different (Taiwanese) manufacturer. These units are called BLU+. The BLU+ designation was devised by the GP32X board members to differentiate the units. On the box the BLU+ is still called BLU. If you are unsure if your unit is BLU or BLU+ you can hit L,R,R,L,R,R,L,L to enter test mode. If the unit is BLU+ you will see the following: "FW Version :1.6.6 (2004.10.10)"

Two issues were immediately apparent when the BLU+ was released:

1) A thick white bar about 1/3 of the way down the screen made some software unuseable.

2) The very top row of pixels (or 'scanline') was moved to the very bottom of the screen in most software.

Much was made (understandably) at the time about these problems, particularly the white bar.
HOWEVER, a software fix for the white bar issue has since been incorporated into almost all programs, apart from a few that are no longer being developed anyway. In addition, sometimes an older version of a program will work ok.

The following emulators have been tested and do NOT have the white bar issue:

LJGP32 (Nintendo NES)
SNES9XGP (Nintendo SNES)
OpenSNES9X (Nintendo SNES) Note MUST be version 0.1!
FGB32 (Nintendo GB/GBC)
Park o rama (Sega SC3000/SG1000)
FSMS32 (Sega MS/Gamegear)
Fgen32 (Sega Genesis)
DrMD (Sega Genesis)
FZX32 (Sinclair Spectrum)
Frodo (Commodore 64)
Atari800 (Atari 8bit)
Phandy (Atari Lynx)
CaSTaway (Atari ST)
GPEngine (PC Engine/Turbografix 16)
FMSX32 (MSX)
Doom
Mame (Arcade)
Fenix homebrew games

The 'moved scanline' issue has been harder to fix. Most emulators do not APPEAR to move the scanline, despite no fix being incorporated into their code, reason being as most games have borders it is almost impossible to tell whether the scanline has been moved or not. Even (rarely) when the scaline is clearly moved it is a VERY MINOR issue that is easily ignored as it is so far from the playfield. Generally, at worst a few lighter pixels will appear at the bottom of the screen, very rarely some movement can be observed. Also, the unit plays best when tilted slightly away from the eyes (so that the player is not reflected), which hides the bottom scanline, as the screen is recessed into the body of the GP.

Anything FS 3 or more is way too choppy for me, so as far as I am concerned it is unplayable.
