Working perfectly!!!
All three versions both on VG-8235 and VG8020 after using opfxsd fs0211.rom /U
but I had to hold down the Control key during startup.
(CTRL:Assigns only one unit to each Nextor kernel with a device-based driver.)

If a given slot is not expanded, its corresponding FFFFh value doesn't matter, no?

If a slot is not expanded there is no memory-mapped I/O register at FFFFH. So, you will be writing to whatever is at that memory location. And it’s not a good idea to assume that writing there is harmless, as my story illustrated.

You can also determine if a primary slot is expanded or not by reading at 0FFFFH and write the read byte with its bits reversed. If the slot is expanded the written bits are reversed when read.

It’s much better to just use the EXPTBL flags in the system area which are initialised on boot, because otherwise you will run into the same memory corruption issue I described earlier.

I don't think it could have any problem if you read and write the read bits reversed because if the slot is expanded the same slot will be selected and if the slot is primary you can rewrite again the bits reversed to restore the initial value. I don't think this address acts on a mapper, but yes, it’s much better to use the EXPTBL and copy this table to another page if needed. It's easier and faster.

Hi aoineko,

In case it helps, I have tested the game on a Japanese MSX1 (60hz) Toshiba HX-21, and it works fine
In turbo R ST too

Thanks.
I don't handle 60 Hz yet (I mean I don't adjust gameplay speed to be consistant between 50 and 60 Hz) but it's nice to know at least its working.

Would you be OK with it if I would add the game to the homebrew section of my site? Or any plans to enter MSXDev'21 with this game?

Yes, I plan to participate to MSXDev'21 and I will be happy to enter your homebrew section when the game will be released.

@tfh, When I said « when the game will be released » I meant not yet.
The game is far to be finished and I still using "place-holder" music and SFX I don't own the rights.
So please remove the game from File-hunter for now.

To celebrate the Roland Garros final, here is a new version of Final Smash 0.2.16.
I added difficulty level to the training mode with bigger or smaller areas to target.
I removed the 1 player mode for the moment; I want to focus on finalizing the 2 players mode for the MSXdev'21 (service is WIP).
If there is enough interest for the game, I will try to add the AI mode after MSXdev'21.
Have a nice day!
