Hello,

When using my 1chipMSX with Moonsound, i got a "Not enough Memory RAM" message.
Does it exit a way to solve it ?
Thx in advance.

"Not enough RAM available" is the real message ...

Do you have a ramdisk running?

No, i'm only using an alternative firmware (KdL 2.3), with 4 Mb RAM memory !

When I was developing it I used 4MB all the time. Are you trying to run it from dos1? Do you have a tool to check free ram before starting mbwave

Seems more like a TPA issue to me.

EDIT: or is this complete and utter bullcrap? Smile

I don't really remember if mbwave does a tpa size check at all Tongue

I tried others ways :
- 2 MB mode (1chip switch) => same error message
- tried to use mapper.com (to allocate different memory place => same error message

I don't have any tool to check free RAM ... If you've got one, i'm interested.

TPA ??? !

TOP PAGE ADRESS

is a bug in a page detection routine, when all page numers @ mapper are available with RAM, so if your routine is looking for a fail or a repeated page on some page number, in way to know UNTIL which page is RAM available, that method just fail because it never finds one.

other thing, is as the page register is 8bit, if you hasn't care, it will overflow and shows zero value for indicating 256 pages availables.

A good routine uses 16bits pagecount register. And that way is easily adaptable for dealing with 16bits mappers.

There's MEM.COM for MSX-DOS2, by Vincent (um, D.I.E.).
