Question on saves from original OS to alt OS
« on: July 11, 2015, 03:58 AM »
I have created save files from the 2.09 OS for the Everdrive 64. They end with extensions .eep .fla .sra

I want to switch over to the alt OS found here in this forum. But I tried simply copy/pasting my saves from the old OS, into the new alt OS's (SDSAVE) folder on my SD card.

When I launch Goldeneye, it doesn't recognize it.

Please tell me I can retain my old saves, and if it's simple as renaming the extensions to the names I just gave?

Thank you!

look at ALT64.INI

ext_type=0            ; 0=classic 1=OS64
save_path=SDSAVE         ; save directory inside ED64

as default settings alt64 uses a different save folder and other save file extensions, but you can switch them back with ext_type=1

Code: [Select]
   if(etype==0){
        switch(type) {
            case 0:  str = "OFF"; break;
            case 1:  str = "SRM"; break;
            case 2:  str = "128"; break;
            case 3:  str = "E4K";  break;
            case 4:  str = "E16"; break;
            case 5:  str = "FLA"; break;
            default: str = "SAV";
        }
    }
    else {
        switch(type) {
            case 0:  str = "OFF"; break;
            case 1:  str = "SRA"; break;
            case 2:  str = "SRA"; break;
            case 3:  str = "EEP";  break;
            case 4:  str = "EEP"; break;
            case 5:  str = "FLA"; break;
            default: str = "SAV";
        }
    }

if I switch the ext_type value, will this effect how this OS saves other games than it's used to? I just want make sure its worth changing this value, when it's only two games I really care about the previously created saves for. Also, that text code you pasted. It is not within the ALT.ini. Do I need to manualy insert that into the ALT.ini I have, and if so, where do I position it?

Also, I have a 16GB microsd card, and I have the entire No-Intro set on it (had to select only the USA versions of the W titles games, due to the card actualy being 14.8GB) Anyway, when I insert this OS onto the root of my SD card, I get a glitch when I turn on my 64. The screen stars out as black, then about 5 seconds later, I get diagonal lines all over my screen moving all over the place.

Any ideas? I think what I downloaded is "xbwgebtprf.zip" Is there another OS of yours that I'm supposed to use?

if you really care about your save games, you should make a backup first. ^^

the code block is a snippet form the source code, it doesn't belong to alt64.ini at all.

if you change "ext_type" to "1", it's using the file naming of the original menu, the only drawback is that the integrated gameboy emulator isn't working any longer.
but you could switch to the standalone version

the other possibility is to rename the extensions of your two old savegames to the other ending scheme.

alt64_v1810-64dd_v05.zip is the latest version

ok ill simply rename the file extensions to my saves. I do have backups of them. :-)

I appreciate your fast response! Also, did you happen to see my issue im running into with your OS I posted? I'll try the one you just linked me to later today. :-)

(edit) just inserted the one you linked me to. I'm still getting the same glitch on my n64, when I pasted everything to the root of my sd card.

alt64 comes with the latest v2 firmware included and is using the v2.5/v3 stock firmware, i think there is a newer one with some bugfixes included in 2.09 for these cards.
the bootemulator is the same like in 2.09, so it should be able to run and save all games.

i don't know much about the v3 maybe the rtc isn't working with alt64, neither the resetless saving is going to be.

the only major bonus feature alt64 supports is 64dd conversion rom support.
covers and some shitty emulators aren't really worth mentioning.

i guess it's caused due to file fragmenatation, it always is.

Is that bad? If so can you tell me what steps I should take? I'm assuming  I need to reformat my SD card?

If that is the case, what do I install first? My rom set has a root folder, then inside that, are alphabet folders, then inside those are the the roms.

Thank you for your help!

copy everything to the pc, reformat the sdcard and copy everything back onto the card

hint: if a rom doesn't load it might be 'cause of file system fragmentation.
the ed64 dma transfer is a bit buggy ^^

you can use this tool to make a full low level format and than the windows explorer to format the sdcard with FAT32,
if you ran into such issues.

Great ill get right on that!  One last thing, please. Do I need to hit RESET to save to my SD card with your OS, even though I have the v3 everdrive?
