Ik doe het maar even in het nederlands voor dit specifieke geval
Van 128 naar 640 gaat als volgt

Haal de 128 kB SRAM Chip uit het onderste voetje (ervan uitgaand dat de MSX slotconnector naar beneden gericht is).
Buig voorzichtig pen 30 van deze chip 45 tot 60 graden naar buiten.
Stop dit Ic in het bovenste voetje. Pen 30 steekt dus nu buiten het voetje)
Soldeer een draadje tussen pen 30 en 32
Stop de 512 in het onderste voetje
Zet alle jumperstjes in de 512 stand zoals aangegeven op de print zelf

Sunrise - you probably also know the average KB RAM every Moonsound has? I'm afraid it's still 128KB

I myself have bought a 512KB Moonsound.

It is simply an answer how to act when you are in a situation like guyver describes !
And you donot have such a version !

I think so, yes. However, until some while ago, before the news of meridian supporting the opl4, there probably wasn't much interest in using the opl4 anyway. So, ppl wouldn't be interested in expanding the ram anyway. Now with the revival and the new software, things might change.
So, aiming at 128k just because most of the current users have that it is not relevant when it comes to future software products, released for a new crowd of users. When there is content for 640k, then users will expand their sram. Not the other way around. There have to be products that demand that amount of sram, only then ppl will upgrade.

Take for example the scc. Just because konami rocks, and because you can't 'copy' the scc chip to a disk, many ppl have at least 1 konami cart with an scc chip, and probably some more ram to run those cracked games with sound. When there's content, ppl will upgrade their systems.

But still... one wavekit will nearly fill up a complete double sided disk. And it will take ages to load as well.

Or am I very old-fashioned here and the only one still using disks, drugs and rom packs Tongue

Your MSX seems to be a bit low in the memory department

My MSX 2+ has 256kB, my MSX-Audio 32kB, my MoonSound 128kB... so yeah: all together this is 544kB including VRAM... if you also add the VRAM of my GFX9000 I would cross that magic 640kB barrier Smile

I think it's more adventurous to live with the limits instead of extending the standard. More ppl will get to see your stuff too.

Well, Konami delivered the chip along with their games. If you had to buy it seperately, it wouldn't have been as popular.
I'm sure you won't ship an OPL4 memory upgrade kit with your game Tongue

Zet alle jumperstjes in de 512 stand zoals aangegeven op de print zelfFor all non-dutch visitors a translation. To upgrade the Moonsound from 128 KB to 640 KB SRAM you need to do the following steps:

Remove the 128 KB SRAM chip from the lower socket (providing the cartridge connector is faced towards you).
Carefully bend pin 30 of this SRAM 45 or 60 degrees to the outside.
Insert the SRAM in the upper socket (pin 30 shouldn't be inserted in the socket).
Connect pin 30 to pin 32.
Insert the 512 KB SRAM chip into the lower socket.
Position all jumpers into the 512 KB setting as printed on the PCB.

Let's, for example take my MSX turbo R GT:

  • Over 2MB ROM Tongue
  • 512 KB RAM
  • 128 KB VRAM
  • 32 KB SRAM
  • Moonsound 1 MB Sample RAM (that's how to do it! Smile)
  • Music Module 256 KB Sample RAM
  • GFX9000 512 KB VRAM
  • Video9000 512 KB VRAM
  • 4 MB External Memory Mapped RAM

For a purpose I didn't mention my NMS 8250 with 512 KB RAM, 192 KB VRAM, 2 external 512 KB Memory Mapped RAM and some SRAM cartridges like FM-PAC, PAC and a HBI-55 (just for fun)...

But all this is getting WAY off-topic now Smile

I think it's more adventurous to live with the limits instead of extending the standard. More ppl will get to see your stuff too.Absolutely, which is why our current gameproject runs on 64K RAM Smile

samples occupy more space than code or gfx... anyway.. it's better to continue the opl4/sram talks in the new topic I created..
