Hi Guys,

I hope you can help, I have looked around the forum and found some good guides/faqs but I am still encountering some issues! Please slap me and send to a relevant post if my questions are answered elsewhere!

So I have just purchased a MGH (black 16M (rubbish Tongue version!) I have successfully dumped carts to floppy and they play without issue, I have also used uCon64 to convert megadrive/genesis roms and snes rom to play on floppy on the mgh.

The problem I have is converting roms that are over 1.44mb i.e. games that require more than one floppy. None of the carts I have are over this size so I cant dump and check whats on the disks.

In any case I have attempted with this (for megadrive roms, I have yet to try with snes)

ucon64 -s -ssize=11 --mgd romname.bin

This splits the rom into parts - romname.1 and romname.2 for example.

I rename these to romname_A and romname_B and place them on separate floppy discs.

I select run with disc A and it completes loading then prompts for disc B to be inserted, I do this and the progress bar completes as expected but then nothing happens and mgh crashes and all that is displayed is the 100% progress bar but nothing happens!

Is there something fundamental that I am missing? I have never used one of these copiers before and have found fragments of info all over the place but know I feel I need some help!! Could it be the rom etc?

Any advice appreciated!!

Did you just using just -s? I'm not sure if the MGH has a problem w/weird split file sizes like you are specifying.

As madman said, don't specify a split size. UCON64 will either split it into 8 Megabit or 4 Megabit chunks by default. Who knows how intelligent the MGH loader software is. It may expect a fixed size of pieces for split roms. Or perhaps at the very least it expects a multiple of 2 Megabits. 11 Megabits is a really stange size to split. 12 Megabits will fit on 1 disk if you format it to 1.6MB instead of 1.44MB.

OK yeh, that could be the problem - I only used that size split having read it somewhere purely to make it fit on a 1.44 format floppy.

I'll try both default and 12 megabits. Thanks!

Well only split to 12 megabits if your floppies are formatted to 1.6mb, otherwise they won't fit on a 1.44mb formatted floppy. If it only supports 1.44mb then split to 8 megabits. You could also try splitting to 4 megabits if the other two sizes don't work out.
