Hacking playing DS game on 9.8 Gateway 3DS and(R4 3ds game)

[askara]

so i have gateway 3DS(9.8) installed with both blue and red card and play 3DS game fine but how do you actually play ds game? when i try to run the blue card it give me black screen and i have to restart the DS. i heard you have reinstall the 3ds gateway exploit after you play DS game to run 3ds game again which sound like a pain. is there any easier way where i can run DS game and 3ds together?

i also have a R4 card(pic below) which i use for DS game long time ago but now it doesnt work, something about i need a normal DS to update the firmware. is there anyway to bypass limit that now?

You need to use the blue card in sysnand.
To avoid having to reinstall the exploit each time you play a NDS game, follow these instructions:

1) Install the exploit using the N3DS_ROPInstaller.nds; e.g. Profile Name: slslasher
2) Go to settings and change Profile Name to another one; e.g. Profile Name: slslasher01
3) Launch a DS game, exploit would be gone
4) Install the exploit using the N3DS_ROPInstaller.nds again and it should be stuck

Extra Steps because I want to change back my original profile name
5) Go to settings and change Profile Name to my original one; e.g. Profile Name: slslasher
6) Launch exploit and test, there should be an error.
7) Install the exploit using the N3DS_ROPInstaller.nds again and it should be stuck

Also, make sure you have bluecardfix.cia installed (on sysNAND), which enables old DS-mode flashcarts to work.
