Your problem could be due some common problems;
A:Are you using AKAIO (Acekard All-In-One) firmware 1.4.1 (The [current] latest version of AKAIO)?
B
id you try to format your micro SD with the Panosonic Micro SD formater and try again?
C
id you download the same game(s) from a different website and try again?
D
God forbid) did you unzip the .nds file(s) from the .rar/.zip archives?
E:If you are using AKAIO, are you using the latest AK2i Loader? Make sure that the loader you are using is from 4/20/09 as the one included in the AKAIO Package (1.4.1) does not load game correctly(or at all) with the old AK2i loader.
As for me, I know that both of these games work.
I have a saved game on Dokopan Journey and The Dark Spire.
The Dark Spire is allot harder then Etrain Odyssey.(So I will resort to using cheat codes) Okay! It is more tedious than hard. I mean, one character dies, so I have to leave the spire to go to a temple and revive the character. When a treasure chest drops, I have to use a thief to examine and disarm the trap or it will make my venture harder. Oy, this game is hell.
Let me share with you what I am currently using:
1: Blue Nintendo DSi (United States, English Language Setting, Version 1.3U)
2: Acekard 2i Model 2(Not Spring-Loaded, cardbord Box with orange "DSi Compatible!" sticker.)
3: AKAIO 1.4.1
4: 4/20/09 AKAIO AK2i Loader (Can be found on this website, search for it!)
5: Kingstion, Toshiba, 1GB, 2GB Micro SDs.
Short Version;
1 Check to see if it is a bad ROM Dump (This sometimes happens)
2 Format your MicroSD with the panosonic micro SD formatter.
3 Check to see if you have the latest AK2i Loader for AKAIO
#4 If you are not using AKAIO, dude, USE IT!
5 If all else fails, your problem is beyond my comprehension, then do either of the following;
5.1 Cry
5.2 Smash AK and/or DSi
5.3 PM a Mod or somebody with better experience.
5.4 Buy the game (Always an option, but not the best option.)
5.5 Say "#&%$ this!" and play a different game, and be on your merry way.
Hope this helps.
