Good morning, I have a Sony F1XDJ which works fine, (new capacitors/power transformer) but for whatever reason, when I try and run Moonblaster 1.4 from floppy (downloaded here) I just get a black screen with white text that reads "Ok." I read something about it not running properly under specific settings, so I downloaded the "Project hmm" version. The screen now reads "Loading Moonblaster", but then spits out garbage right before rebooting.

Seeing as how the (scanned) instructions are in Dutch, is there something I'm missing here?

The program needs 128kB of memory mapper RAM. Your F1XDJ only has 64kB... I bet that's the problem.

So then I either have to internally update the ram via modification, or buy a cart? Sorry, I'm a noob while also trying to push through the language barriers.

This might be outside of the focus of the original question, but where there any standout utilities/games to run within the original 64k? It seems people are quick to talk about programs that require 128k+, but not so much in the other direction! oO

That’s a very nice machine! And also nice that you got it recapped Smile, it’s a bit notorious for that.

As for additional memory, you can just use a memory mapper cartridge. I recommend to buy an all-in-one cart like a MegaFlashROM SCC+ SD with the 512K RAM option, or a Carnivore2 (alternative). Then in addition to RAM you also get large SD / CF storage, DOS2 with subdirectories, ROM mapper emulation, additional sound chips, etc. Loose memory mappers are also available however I think the all-in-one carts are both more convenient and more bang for the buck.

As for nice utilities, DD-Graph AGE5 is a good drawing program for screen 5.

Thank you for the detailed reply! I see that the carts are 140 Eur for the option I'm looking at. I'm positive it's 100% worth the money, no question, however if money is tight and I have loads of free time, would I be okay to upgrade the internal memory to 512k via modification and continue to load from floppy if I'm just looking to run something like Moonblaster?

Did I mention I have loads of free time? Cool

Sure yeah that would also work. I quickly searched the forum for the internal memory upgrade, there’s this thread.

Seems like it has an S1985 engine which should make an upgrade to 512K easy, but apparently it does not use it for the mapper but has a separate circuit so the upgrade may be a bit more complicated than it needs to be, but still, it’s possible.
