EverDrive-GB OS v2

How do you update? You just place it in your home directory? Run it?

you place it in the EDGB folder and pray

Here's my test results, using the same microSD card:

US Super Gameboy: Works.
JP Super Gameboy 2: Works.
US Gameboy Advance (non-SP): Reboots into last loaded game.
US Gameboy Player on US Gamecube: Reboots into last loaded game.

Has anyone out there gotten v2 working on a non-SP GBA or the Gamecube Gameboy Player?

I found a reason for my problem - it's sd card. EDGB is picky aboud sd cards, but OSv2 is even more demanding.
I started swapping sd cards, and absolutely unbranded 2G microsd card from aliexpress worked! silicon power 8g microsd(hc) booted OSv2 only on classic brick, verbatim 8g microsd(hc) made EDGB to show hex error on power on.

So, now I got OSv2 tested working on: Classic DMG-01, Color CGB-001, Advance AGB-001, Advance SP AGS-101.
Format tool used: windows format to FAT32, sector size 4k.
Card used: noname 2gb microsd card (only one that worked for v2 on every device I could test)

what are are class speed and seek time of these mircoSD cards?

Just tested on my Super Gameboy and Gameboy Player. Both work fine, booting to the main screen.

SP and Verbatim are class 4, unbranded card is, well, 2gb in size. No more markings on it. Under seek time you probably mean access time - I have to run IOMeter to test, will do it later - repeatable test setup consumes some time.

32GB SD card need be Class 10 anything less than 10, will fail to load OS
16GB SD card need be Class 8 anything less than 8, will fail to load OS
8GB SD card need be Class 6 anything less than 6, will fail to load OS
4GB SD card need be Class 4 anything less than 4, will fail to load OS
2GB SD card need be Class 2 anything less than 2, will fail to load OS
1GB SD card has NO class ranking

Access Time need be 0.81ms or lower, anything more than 0.93ms, will fail to load OS
(according to sd2snes' sd card page)

Error most cause by sd card is:
FAT32 system file is corrupt by bad blocks or fragment files

This also complies with any other Everdrives

This is a good answer, but it still eludes me why same everdrive gb with same sd card boots os v2 on gameboy classic, and refuses to do so on gameboy color and advance.

v2 on gameboy classic, and refuses to do so on gameboy color and advance.

Perhaps because Gameboy classic has lower cpu clock.

I've got a few 1Gb, 2Gb, 8Gb and one 16Gb - could only get v2 to boot on a brick GB, kept reseting on the GBC. The only cards that worked OK on the brick were an unbranded no markings 2Gb and a class 10 16Gb. None of the other cards I have would boot into v2 on either.
Too bad it won't work on the GBC without a randomly lucky card :/

Unbranded 2GB micro SD gives me the error 0xD2.
Another Toshiba class 4 micro SD boots directly to the game already flashed onto the cart.
Sadly i don't have another micro SD to try at the time

I'm on a 8GB SanDisk I think class 1 card, and it doesn't work with the new OS on my GBC's. Any plans to fix the issue KRIKzz?

These issues are likely hardware issues due to card speed etc.

[gojira54]

If it is a hardware issue how come v1 works OK on most cards when v2 doesn't run on the same card? Must be the way the code is operating

your sd card does not meets standard of speed of that size

Because OS v1 is built-in on EDGB board and OS v2 is on SD card
If sd card is too slow, EDGB will fail to load OS v2

Ah OK 
Off to buy 4gb 10spd...
