Unfortunately the answer to my question is no. The address seems to wrap around to 0 instead of proceeding into the extra 2K. @matthew180 would it possible to fix this in a firmware update? I'm working on a project that requires 30 ROWS, ECM3 tiles (6K), ECM3 sprites (6K), 2D scrolling (4K), TL2 (1K) plus 256 bytes for tile attributes and 128 bytes for sprite attributes. Without the extra 2K I can only store 32 sprites patterns, which is simply not enough. All 256 tiles are also needed.

Does it work to set your 6K ECM3 sprite pattern table at >3000 and let it extend into the extra 2K at >4000 to >47FF?

Anyway, here's a cartridge image of you program, so that FinalGROM owners don't have to use E/A to load it. 🙂 snp8.bin

Or maybe the user put SNP on his FinalGROM and thought it could load from there (which it can't because it's not a cartridge image)?

So what you're saying is that you can load SNP from E/A loaded from FlashROM99. But that's not the same as loading SNP directly from FlashROM99. To do that you need to convert SNP into a cartridge image.

If you're running Dm2k_fr99.bin then that's a cartridge image.

FinalGROM99 and FlashROM99 run cartridge images. SNP is a disk file (E/A#3 file) - not a cartridge image.

New software is what I mean. 😃

With all this interest in F18A I feel inspired to do something new for the F18A.

Which version do you mean by Eric's file?

The file from post #13 also works for me, but none of the versions that have groms work.

That would certainly explain it. But why it works for Fabrice I don't understand. Are there different versions of the FG?

I did rename the files. I have attached the files I use to my last post.

The same thing happens if you try to play it without 32K RAM, but I do have 32K. Is it working on the FinalGROM for anyone else? rockc.bin rockg.bin

No I, think we should all use the latest version.

OK. Do you use version 1.9 of the F18A firmware? Some of the demos have been done for earlier versions of the firmware, and in 1.9 some features were removed.

Hmm, it doesn't work on my FG either, with the same symptoms. And not with the version @Eric Lafortune posted either. They work fine under emulation.

I have plenty of demos. Does "I somehow displaced my FinalGROM99 SD-Card" mean you cannot use cartridge images? super-mario-bros-8.bin F18ADEMOS.dsk F18ADEMOS2.dsk racing.dsk raycaster8.bin

I think you could easily end up with orders for a 200-300 units. 🙂

No matter what hardware issues might exist, the software must also be doing something special compared to all the carts that work fine with the FG and sideport attachments, right?

You need both RockRunnerC.bin and RockRunnerG.bin.

Better to use the new version built from the source code. RockRunner.rpk RockRunnerC.bin RockRunnerG.bin

Here are my findings for Tutankham: FG with no side port attachment: Always works FG with speech synth: Never works FG with SAMS memory: Works 4 out of 5 times

I hope this will help with the orientation. texcaster.rpk texcaster8.bin

Yes that should be possible.
