Graphics Glitch in Neo SD Menu and in game

26 Jun 2019, 20:14

Hi,

I've just recieved my Neo SD pro this monday and I'm disapointed in these glitch issue…

I tried to change the power supply (megadrive 9V 1A and 10V 1,2A, generic 9V 2A) with no success. I tried different memory cards, roms and… no success...

Of course my Neogeo works very well with my geniune games.

There is a solution about this issue? Or i need to open a request for an Exchange

Thanks in advance for your help

If you hit the reset button, does the glitches go away?

Thanks for your answer.

Frequently yes, but not always.

Drop us an email to support (at) terraonion.com

Include details of what is going on and serial number of the cart. We can get you an alternate firmware, but it might be a couple days as we are swamped at the moment.

HI,

Thanks for the alternate firmware, the majority of glitches are gone away.

Anyway, some annoying bugs remains.

Test protocol :
1- I've tested with two NEOGEO (3-4 and 3-6), with original PSU. The bugs are exactly the same on the both.
2- I've tested with OSSC and Sony Trinitron. The bugs remains exactly the same on the both.
3- I've tested my rom set with my NEOSD PRO and with another NEOSD (non pro). Same NEOGEO (3-4 and 3-6) and PSU. No bug with the NEOSD (non pro), everything work like a charm!

Bugs reported :
Metal Slug 1 : some graphical glitches.


Metal Slug 2 : Graphical bug in second plan. The effect on the sand is not correct very jerky.

World Heroes : Graphical bug in first plan. The floor seems unstable very annoying when playing.


My questions are :
- Is my NeoSD pro defective?
- If not, there is an available fix?
- If not, are you planning on working on futur update to fix it?

Thanks in advance for your answers

Regards

That happens in games that user raster interrupts, because the in game menu button check eats some execution cycles and causes misalignment of the raster effects. If you disable in game menu trigger, they will work fine.

Thanks for your answer neodev.

Test done. In fact, the issues in Metal Slug 2 and World heroes are almost gone. The graphical bug remains but they are ligther.
However, the graphical glitches in metal slug 1 are still the same…

Are you planning some fix about these issues in the futur? Installing an unibios 4.0 can fix Something?

Thanks in avance for your answer.
