A save problem with Pokemon Crystal version
« on: February 06, 2019, 10:36 AM »
I have got my x7 recently and I'm very love it cause the great perfomance.

Then when I was trying Pokemon Crystal,the game which was one of the most important reasons made me bought the X7

the problem is that after I have selected the heroine,saved games and reset GBA,then I turned on the switch again, started the game,

then the heroine has changed into the boy character but still kept the heroine's color.

This game runs perfect on VBM, and the save file is clearly 64k size,but in X7's save file it will become 32k size.

Someone told me it would crash if I ignore the problem, I really want to play the Pokemon Crystal in X7 ,hope you can fix this , thank you very much Klikzz ;D ;D ;D

Don't use the emulator save directly. Place the save file in other place on sd card and use the copy do sram function from OS, by selecting the save file in this place, after only loading the game.

Go to target game, press A once and select load only, then pess A on the save file (grab another known good copy from pc)  and select copy to sram, then press start.

The OS seems to do some sort of treatment to the save file when doing this, but loading directly it assumes the file is already correct, causing issues.

pokemon crystal original cartridge game save type :32KB SRAM.
so, save file size should be 32KB . Not 64K.  64KB is wrong.

I'm pretty sure it doesn't, Pokemon 2nd gen requires RTC thus they all used MBC3, which only supports 32KB SRAM from various materials I've read.

VBM got save size wrong sometimes is a known fact.

Pocket Monsters - Crystal Version (the japanese version) uses the mapper MBC30.

Pokemon Crystal (the north american and other localizations) uses the MBC3 mapper.

The japanese version had more things that were cut from other locales version.

Maybe the problem is the everdrive simulating the mbc3 with a game that requires the mbc30, assuming OP is using the japanese rom.

I'm surprised the Wikipedia I got this mapper info I added to my final version of EDGB had some flaws after reading that, I presume that also explains why Goomba cannot support Crystal too when used on the GBA... https://imgur.com/a/8FftG9Z

My guess is that only Krikzz will be able to tell what happens when "Pocket Monsters: Crystal version" is loaded using a Everdrive.
