EverDrive MD / Re: Error54 after reset on Everdrive MD V3
« on: November 22, 2018, 03:16 PM »
I also have this problem on the same ED MD v3 which is giving me headaches about SDHC cards (see other recent thread)

EDIT: meaning I have this same problem but only with regular non SDHC cards which are not recognized anymore by my everdrive (even after formartting fat32 with 32kb clusters)

So the subject says it all. My ED-MD v3 is running mdos.bin v2 and it now only recognizes regular old SD cards, which are limited to a mere 2 GB which is not enough for my needs.

The card that is not recognized anymore is a SDHC integral ultima pro 4gb class 6, regular size. A microSD 2gb is still recognized, as well as other  full size SD cards of 512mb and 1gb from different brands. The only one that isn't working is the SDHC one.

I've already tried lots of things, switching pad, power brick, etc. I'm on a Genesis 1.

The ABC test fails only at the last stage (SPI) and I canĀ“t run it when with a 2 GB card or less (non SDHC). Also the C button seems to launch the game as it was the start button...

My ED is 4-5 years old: is it dying? (also I have used it just a few times in all those years...).

EDIT: I found this sub-forum so I moved my problem here.

Thanks

EverDrive MD / Re: multirom tool update?

ok thanks!

So could you use a custom mapper based on the Mega Games 10 offical rom ? Or something else ? The ideal setup would be a mapper that adresses each game at 128 KB chunks, just like the SSF2 mapper does the same at 512 KB chunks, ie when a game is 768 KB it takes two and the next game starts at the 1536 KB address, and so on, right ?

Do you consider updating this tool anyway ? I think a lot of people would apreciate and use this tool. As I was saying it is not known among the Megadrive community.

thanks again!

Thanks Krikzz,

so could you make the same tool without the SSF2 mapper, even if it is limited to 4 MB (32 mega, the real limit of the original games) and avoiding this 512 Kb limitation ?

As you can see, this tool has a lot of potential. Turning on my Megadrive WITHOUT the SD card in the everdrive but being able to choose between 13 games is awesome. If I could choose between many more (4 MB is still a lot of space), that would be even more awesome.

Megagames 10 used the menu system (and mapper, I guess) of previous 3 in 1 games collections. It's a 4 MB rom.

Thanks!

EverDrive MD / multirom tool update?

So as I was praising here http://www.sega-16.com/forum/showthread.php?20630-Help-making-multi-game-selection-menu-for-homebrew-ROM&p=661876&viewfull=1#post661876

Krikzz's multirom tool is awesome:
http://krikzz.com/pub/support/index.php?dir=edmd-v3%2Ftools

But it is limited to a 13-in-1 multigame rom (56 mega, which is the limit of the Everdrive, including the menu), because each game take chunks of 512 KB (i e Strider takes two of them) so Columns take one full chunk even if it is only 128 KB.

I realized that the entire Megadrive sub 4 Mega (= 512 KB) catalog (28 games) fits in ONE rom. The same goes for the SegaNet whole catalog (26 x 256 KB games). But due to this limitation, the rom is already full when combining 13 games using this tool.

So could you improve the tool as to take it into account the real rom sizes? Is that possible ?
Also would it be possible to have any kind of menu customization? (image, rom names...)

I think it would spread the awareness of the tool and therefore the everdrive/megaeverdrive itself. It is very convenient to leave one of those big roms loaded and come back to the console and not have to worry about loading times each time you want to swith from one to another.

Also this could be helpful for people wanting to do real cart 32 Mega compilations, like the excellent official Megagames 10. I'm not of those, though.

Thanks in advance for your reply!
