So, since the C4CPC is not available for quite some time (and since mine seems to be failing now), are there any options to get some games on a GX4000 that don't require to create a single cartridge per game?
I remember that there have been some 32-in-1 cartridges on Ebay a few years ago, but they have disappeared and I also can't find any reference how to create them.
Would it be possible to put more games on a single EPROM and get a menu to choose from a list of games? Maybe through NOCART (and maybe a way to support 360K discs on a 512KB Eprom)?
This guy sell various variants:

I've already ordered a few items with this guy (ConnyFox): a trustworthy person, excellent communication and follow-up for shipping, and good contact for after-sales questions. 👍
I've not heard from anyone using one yet, but there's also the BackBit Pro Cartridge that has GX4000/Plus support: https://store.backbit.io/product/backbit-pro/ - a bit pricey, but you can put in an order. It was available till quite recently, looks like it won't be till 2023 now though...
