Hello there!

I do know how to access to FMPAC's SRAM and I would like to know if PAC's SRAM is accessed in the same way (same address). I could not find information about this cartridge on the net (maybe again I'm blind) and I don't have it either.

Could anyone state if it acts in the same way that FMPAC?


Thanks in advance!

Your in luck. The Fmpac does have a battery

Heheheh, I know, I know...
But if Moonsound keeps its information in SRAM after a MSX reset, it is useful for me too, so don't worry, I will use it.

It is just that I am lazy to read the whole information to do it through OPL4... but I will do that later, someday.

Why am I a so bad ASM coder? Else I would do it asap.

I can give you an set address, ramtosram and sramtoram function for the opl4.. save you some reading

That would do me a worse codeR even!

But of course, you can send me it, you will be credited after I finish my "job". Your name was "Anne de Raad", right?

Seriously, that would be nice of you. I don't want to focus all my job in SRAM but in other parts more important right now... and as I am "learning" now, that will save some time.

Thanks!

to be able to access the PAC SRAM you need to write $4D to $5FFE and $69 to $5FFF in the PAC slot... then the SRAM will appear in the area of $4000-$5FFF in that slot... be careful though, writing $5FFE and $5FFF with other values will disappear again.

it's identical to the FM-PAC one. though the PAC has no ROM to detect it so you need to do detect it in a different way.

Thank you, BiFi! I needed to know if they were identical ways to activate it, so it makes it easier.

Well, I will try to detect it in a more rudimentary way, but as I don't have a PAC... well, no problem, I hope it will work.

you're welcome... I made an SRAM manager source about 10 years ago, though I didn't know back then the PAC doesn't have any ROM so it should be detected in a different way... which still needs to be coded. ASCII8 SRAM, FM-PAC, the Sony HBI-55, MSX-turboR are implemented in that source... ASCII16 SRAM still isn't... maybe I need to update the source

Now I have most of them implemented... just that Sony HBI-55 is missing here (and of course, Moonsound).

But I just need find the cart and write/read from there, not that difficult...

What are you going to make SeabeMSX?

Right now... remembering how to code and learning. Later a nice util, I hope. But I don't like to make it public until I have something working, sorry.

So shut up Anne!!!

newbie coder learns to cope with user whiners

don't get discouraged by this though... it gives you a certain power keeping users waiting for your great developments

Yes Anne, shut up!

how does it feel talking about yourself in the third person?

/me not Anne
What's ya making Saeba-san? :-P
