pokemon diamond saving help

i finally got the game to work and i saved after i was done playing. now whenever i try to open the saved data the screen just goes black and nothing happens. whats happening here?

This happened to my friend often. Try deleting your emulators config file and reloading. You won't lose your save game.

what MC that you use?? R4, M3??
try to update the firmware..

You using flashcart or emulator?If you're using an emulator, then go here for some help.

I'm using no$gba and the same thing happens to me, it just goes black when I try to continue my game on Pokemon Diamond. I've visited the link above and copied the settings. The settings on my no$gba are:
Emulation Speed, LCD Refresh - Realtime, Auto
Sound output mode - Digital Stereo
Reset/Startup Entrypoint - Start Cartridge Directly
Sound Desired Sample Rate - High (44kHz) Best
Video Output - 24bit True
3D Renderer - nocash
Multiboot Port - None/Disabled
GBA Mode - GBA SP (Backlight)
Multiboot Normal/Burst Delays - Fast/Fast (Best)
GBA Cartridge Backup Media - Auto
Number of Emulated Gameboys - 1
NDS Cartridge Backup Media - Auto
Link Gamepaks - Gamepaks in all GBAs
Solar Sensor Level - Bright Sunlight
Link Cable Type - AutomaticBut still when I try to load my saved game it goes black for ages. Pretty much I am not able to play my saved game. PLEASE HELP!

This is the one that I've used. I play and finish the game with this setup.The first side:
1. Unlimited MHz Disaster , 10%
2. Start Cartridge directly
3.1 - 24bit Ture color
3.2 - nocash
4. GBA SP (blacklight)
5. Auto
6. FLASH 512 BYTES
7. DarknessThe other side:
1. Digital Stereo
2. High (44Hz) (best)
3. None/Disabled
4. Medium/Medium (stable)
5. 1
6. Gamepaks in GBAs
7. AutomaticBTW the game freezes if you change the sound output mode to none. Hope this help.You need to choose the NDS cartridge backup media yourself. The auto setting doesn't work right. Every game has its own NDS backup media. You need to choose the right one for different games. i.e Pokemon Diamond(FLASH 512BYTES) but Digimon World DS(FRAM 32 BYTES)
