SD card problems

Topics regarding the Uzebox hardware/AVCore/BaseBoard (i.e: PCB, resistors, connectors, part list, schematics, hardware issues, etc.) should go here.

right! But I think you told it in an earlier post.
You always have to get up from the couch if you want to load a new game :)
The last digit of Pi is 7! I calculated this, as I counted to infinity yesterday!

Please, keep that feature/bug! It was my only way of doing sport! :lol:
Now, seriously, an IR reciever plus a remote control would be something cool.
I know i'm too young, but it doesn't matters. Maybe i'm a newbie, but i can learn very fastly

I simpler solution used by most hand held systems would be to add a function checks when L_But, R_But, SELECT, START are pressed at the same time would reset the system with the reset() command.

This might be a feature that could be added to the core.

Yeah that would be the best solution!
So all the games have to be updated!

The kernel already includes a reset combination as mentionned in an earlier post. It is checked when the joypads are read during vsync. If select+start+y+b is detected, the watchdog reset is triggered. This feature is part of the kernel since V1.

I made a simple HEX to get the speed capabilities of the SD cards. Can you checks you card on it and report the TAAC & tran speed values? That could help in making the gameloader (and the SD api) adapt the SPI bus speed in function of the card's speed.
