FDSkey gives me Error 03 while attempting to save
When FDSKEY plays some games that need to be archived, a 003 error message will appear. Other games that do not require archives can be played normally. Is it a RAM problem, a FDSKEY problem, or an SD card problem?
I have tried using an SD card to play a game that requires a save file and it results in error 07. Can you try with another SD card
Hi! What you mean by "archived"?
It means this game has a save function，
Nazo no Murasamejou (1986)(Nintendo)(J)[tr En].fds
Metroid (v1.02) (1986)(Nintendo)(J)[h3].fds
I get this when trying to load specific games as well - just got my FDS RAM adapter today and could not get Akumajo Dracula (the first Castlevania) or Metroid to save (or in Metroid's case to even load the game after trying to create a save file). ERR 03 as well. Tried the same disk images on an Everdrive and no issues. Is there a setting on the FDSKey to 'allow' writing to disk?
Where did you use it? @kalm-traveler
You must pull-up write data line to VCC via resistor (5K-20K) if you want to save game progress, because Twin Famicom has no pull-up resistors inside it.
@donly thanks for replying!
I figured out (probably) the cause in my situation - the file set I was using doesn't seem to have headers, which the Everdrive doesn't care about but it seems to trip up the FDSKey.
I definitely re-ripped my full library of FDS disks to have headers cough cough and now the FDSKey does not have that ERR 03 anymore with any.
Using the FDS RAM adapter on a Lava FC (the Chinese "Famiclone" that uses real Nintendo CPU and PPU in a modern PCB with all other parts new and FPGA for generating all the analog outputs as well as HDMI on the top version).
Everything works flawlessly now after I definitely re-dumped the entire disk library with headers ;)
