Hi Gdx,

Please check again Eagles5,

In HB 20P the ship goes automaticlally up to the top of the screen
In NMS 8245 the games freeze and I have to reset the computer, then the games begins ok (it´s seem that the games it´s keep in RAM)
In Tr ST you only can move the ship right and left (no up and down)

At least in my Eagles5.sms version

Concerning Eagle5.sms : no need of sg-1000 loader, just use it as a MSX rom (in blueMSX, it works as mirrored rom in MSX machines and with the SegaBasic mapper in Sega machines).

Hey mars, are you saying that some SMS roms work without changes on MSX machines or only using BlueMSX (or maybe OpenMSX) with some tricks?

Btw, great work gdx!, there're some cool roms in SG-1000 Smile

Yes, there are some common roms between MSX and SMS.

For Eagle5.sms, take a look at adresss 4000, you'll find the 41 42 MSX signature !

Some little Korean SMS roms (Sky Jaguar for example) have also this "feature". It does not work if other changes make the rom incompatible with MSX.

There are also 4 common megaroms : http://www.smspower.org/Tags/MSXCompatibleROM

That is pretty cool if you ask me.

I wonder if this means the games were developed for MSX first? Do the MSX versions of these games work on the SMS?

No, the MSX versions of the games don't work on SMS.

I can't fix it today. I do not understand the cause.
I have a MSX version. It has the same problem. oO
Same problem on OpenMSX but no problem on blueMSX.

The MSX version of eagles5 which I have works perfect in the First Megaflash rom ( 512kb / OPF )
