a) Does the open source cross platform myth writer support Neo Myth Menu v2.2 ?
b) Does the open source cross platform myth writer support 1024M with Neo2 Lite/ Neo2 Pro ?
no to both counts.
Hmmm, I see. Thanks for the information anyway!
for now I'm adding snes support, n64 will have to wait a few months.
Nice to hear that SNES support is coming! Hopefully mic_´s great menu will be added.

actually someone might jump in and implement n64 support, all that needs to be done is write specific values to specific locations, everything else is the same between all the myth carts.
that's what open source is for!
I doubt that there is someone willing AND able to implement those specific values.

1024 mb cart is a little trickier than the n64 support though.
Hmmm, again. The 1024M cart (Neo2 Lite or Neo2 Pro) has the biggest flash memory which is used for some N64 games, e.g. Paper Mario, Ogre Battle, Conker, Resident Evil. I (and probably most N64 users) would be very happy if 1024M will be supported some day...
