Mame Save/Load State with One Button. Need help finding file to edit.

[arcadeswede]

Hi!

I'm trying to find a way to make mame save/load my state in a game with ONE single button.
Now I have to press for example: F5 and then A to save my state, and the same way with loading the state.

I found this thread in the forum:
http://forum.arcadecontrols.com/index.php?topic=33233.0

But I can't find the file in the mame source folder that they are talking about (I'm using mame 0.143).
It seems like the version they have is an old one though.

I have Mame 143u1 and I know how to compile.

Could someone help me find this code (file) to edit?

Regards
Victor

Right now i have save to: joy down + button 1.  But then it asks where to save it to and thats where im stuck too   I want it just to save auto to slot 1 and load from slot 1

[arcadeswede]

Yeah, that's exactly what I'm looking for!
Just one button to quicksave and quickload.

I don't care about saving/loading from different slots.

Hi guys....

I too am looking to figure out a solution to this problem.

I have mapped out a save state configuration on my arcade cabinet buttons, but I'm them presented with a 'Select position to save to' prompt.

All i would like it to do is save it to slot 1 for example. Then on the load state map I've set up, I would like it to just load the slot 1 and not prompt me with the 'Select postion to load from' prompt.

Any solutions to this would be fantastic Any mame cabinet gurus out there with any ideas?

Thanks in advance.

I hold mapped out a drop tell configuration on my arcade compartment buttons, but I'm them presented with a 'Select opinion to book to' punctual.

All i would equivalent it to do is reserve it to interval 1 for lesson. Then on the weight suggest map I've set up, I would equal it to virtuous worry the interval 1 and not fast me with the 'Superior postion to sedimentation from' punctual.

Not sure what your getting at kalice63... I think I will need to down a few pints and several shots of vodka to make sense of what you wrote pal!

Anyone find a solution for this?  I hate having to keep a keyboard around just for that

[equlizer]

Bump for an old topic that still has not been solved.

I don't really see how a single button can be used for load AND save.  How would MAME know which action to perform?  It's not exactly like it's a toggle action.

[equlizer]

1 button would be to save to state 1 and 1 button to load state 1.  2 separate buttons.  2 separate functions.

I would also love a way to set up an easy save/load system. My buttons are all connected to u360's and therefore have no number value. Perhaps this is something we could ask the mame devs to implement?

I found this but dont know what to do with it:


#IfWinActive, ahk_class MAME ; MAME

F7:: ; SAVE

Sleep, 30
Send, {F8 Down}
Sleep, 30
Send, {F8 up}
Sleep, 30
Send, {m Down}
Sleep, 30
Send, {m Up}
Sleep, 30
return


F2:: ; LOAD

Sleep, 50
Send, {F9 Down}
Sleep, 50
Send, {F9 up}
Sleep, 50
Send, {m Down}
Sleep, 50
Send, {m Up}
Sleep, 50

return

That looks like an AutoHotKey script.

now im having issues with mame not saving games.  when i press the key to save i get the error: failed to save file or failed to open file for load operation

This can only end in tears.

I was fairly easily able to make this change to a Mame 0.156 build by editing the src/emu/ui/ui.c file to no longer prompt for the file selection but to instead just hardcode the file to 'a'.  After that change, I was able to map one of my arcade buttons to save and one to load and it works like a charm.  If anyone would like to know how to make this same change then just let me know.

Since Mame "i don't remember" until Mame 169, you can do that (every button load/save cheat)  if you remove these chapters in UI.C or UI.CPP:

// okay, we're waiting for a key to select a slot; display a message

and

// check for A-Z or 0-9

I know it worked already with mame 127 but before, i don't remember, need to test.

Until Mame 169 there was no problem to compile with this modification, but since mame 170 this cheat does not work anymore, i have to search.
