.sav file not being picked up

Moving the thread here:

dumb question: I have a pokemon blue ".gb" file and ".sav" file. But when I start pyboy from the terminal with

python3 -m pyboy "Pokemon - Blue Version (USA, Europe) (SGB Enhanced).gb"
it just says "new game". Doesn't seem to recognize the save state.

@BET Adsorption so I just change by .sav file ext to .state?

Tttv94 @BET Adsorption so I just change by .sav file ext to .state?

BET Adsorption•1/7/25, 12:18 AM

to .sram maybe

ttv94OP•1/7/25, 12:22 AM

oddly still doesn't work. Just says "new game" with no option to continue

BET Adsorption•1/7/25, 12:23 AM

and the name of your rom file and save file?

thatguy•1/7/25, 12:23 AM

Make sure it is in the same directory as your .gb file

BET Adsorption•1/7/25, 12:23 AM

ls -l for me

BET Adsorption•1/7/25, 12:24 AM

name them something sane too. maybe without spaces. blue.gb blue.sram

ttv94OP•1/7/25, 12:30 AM

I also tried renaming them each to blue.gb and blue.sav but that didn't work. Lastly tried copying blue.sav and relabeling as blue.sram but that didn't work either

ttv94OP•1/7/25, 12:30 AM

same directory

thatguy•1/7/25, 12:31 AM

That doesn't say blue.gb and blue.sram

BET Adsorption•1/7/25, 12:33 AM

and just new game?

Tthatguy That doesn't say blue.gb and blue.sram

ttv94OP•1/7/25, 12:37 AM

yes, I was showing you the starting directory files so we could work from step 0. I renamed them as you asked - happy to send more screenshots if needed.

these were created automatically using the Epilogue GB Operator.

BBET Adsorption and just new game?

ttv94OP•1/7/25, 12:37 AM

correct, does not say 'continue'

BET Adsorption•1/7/25, 12:39 AM

her eyou want

BET Adsorption•1/7/25, 12:39 AM

blue.gb blue.gb.ram

BET Adsorption•1/7/25, 12:39 AM

blue.gb.state

BET Adsorption•1/7/25, 12:39 AM

try that

BET Adsorption•1/7/25, 12:40 AM

then run pyboy

BET Adsorption•1/7/25, 12:40 AM

THEN

BET Adsorption•1/7/25, 12:40 AM

press X

BET Adsorption•1/7/25, 12:40 AM

it should load the state

ttv94OP•1/7/25, 12:43 AM

interesting - got assertion error. Note that "blue.gb.ram" only existed after starting pyboy not before. The Epilogue GB Operator can only create .gb and .sav files

BET Adsorption•1/7/25, 12:55 AM

open pyboy, press z to save a state

BET Adsorption•1/7/25, 12:55 AM

make sure that state is correctly named

BET Adsorption•1/7/25, 12:55 AM

then try to load it with x

BET Adsorption•1/7/25, 12:55 AM

i am assuming your save state is not going to work as-is

ttv94OP•1/7/25, 1:04 AM

weird, I just got it to work with the mGBA emulator - so it looks like it is a pyboy issue given multiple emulators can pick up on the .sav file

@Bækalfen

thatguy•1/7/25, 2:01 AM

saving a state is different than saving a save file

thatguy•1/7/25, 2:02 AM

Remove everything but the rom from the directory, save the file and check the name/location of it. Also see if that file can reload.

On PyBoy the file is not named , but , as you might have found out. The error in the screen shot is you pressing ctrl-c, so does it work?

Bækalfen•1/7/25, 8:37 AM

Ah, I see the assertion you mean now. You can send the / file (not the ROM!)? Then I'll look at it

Bækalfen•1/7/25, 8:38 AM

You can also add to the command line. Maybe it tells you something more

Bækalfen•1/7/25, 8:47 AM

Your file is the right size, and PyBoy reads banks at a fixed 8KB banks. So the only dynamic part is if your ROM reports too many banks (more than 4).

Bækalfen•1/7/25, 8:49 AM

This is how it should look:

Bækalfen•1/7/25, 8:49 AM

Notice:

thatguy•1/7/25, 12:08 PM

Unlikely but is it possible it's in a gbc format?

Sky•1/7/25, 3:41 PM

Have you tried inizialining pyboy with ? It shouldn't make any difference on the save, but it's worth a try

Bækalfen•1/8/25, 5:32 AM

Shouldn’t matter for that part of the code where the error is
