SCCCONV.exe is a tool to rewrite the "CALL 0093H" in the program to another address.

For example, using the SCCCONV.exe, please rewrite the "CALL F750H" the "CALL 0093H" of METALGEA.ROM.
Then, "CALL 0093H" is rewritten to "CALL 0F750H", METALGEA_SCC.ROM is created.

However, you can not do anything just this ROM.
You must start the NandemoSCC earlier than this ROM.

In blueMSX, after starting the MSX-DOS from disk, and then set the SCC cartridge in slot 1, and set the METALGEA_SCC.ROM in slot 2.
Then, start the NandemoSCC, the "BOOT" is changed to "ROM", the "PRG ADDR" is changed to "F750H", please to start.
You will enjoy the METALGEAR in SCC sound.

4-5-6 option of NandemoSCC is turboR only.
Because it is using a DRAM-MODE that exist only in turboR.

With DRAM-MODE, it is possible to rewrite completely the BIOS, it does not consume even first 64KB of MAIN-RAM.
So, you will be able to operate even in the software disk version.
Even if have many RAM, does not work with MSX2+.

Incidentally, Ys I- II- III, Since the rewriting a program so as to correspond to the SCC, it is different from algorithm of 4-5-6 option.

Hi Tiny Yarou,
First of all I want to thank you for your efforts. It is a remarkable discovery Smile

I thought that using the sccconv.exe would change the rom, so it can use scc without the NandemoSCC tool. (Just like with ys1,2 and 3)
So, convert the rom, put scc in slot 2 and the converted rom in slot 1 and then boot your msx.

If you still need the NandemoSCC tool, what is the purpose of the converting tool. I can hear metal gear in scc fine without have to use the convert tool.

The converting tool is intended for MSX2 or MSX2+ users.
If you have a turboR, because DRAM-MODE is available, you will not need the converting tool.

@Tiny yarou: Okay, I've tried it with openMSX. I use NMS 8250 with nandemoscc disk and converted metal gear (using option 3), I get syntax error in 0 error. But it's okay, it works fine with Turbo R and I adapted sccboot.rom to match 8kb so it works with openmsx. If anyone needs this adapted rom let me know.
But once again, BIG compliment for you Tiny Yarou, playing metal gear with scc is like a whole new experience Smile Thanx again.

How to use with a real Turbo-R and a MegaFlashROM SCC+ SD? I can't get it to work...

Use OPFXSD SCCBOOT.ROM /k5 /u
Insert the MegaFlashROM SCC+ SD in slot 1
Insert a cartridge game in slot 2 (i.e.:King's Valley)
Turn on the computer and hold SHIFT key.
In NandemoSCC menu press 4 key and SPACE to boot the game (you can tune some options like SCC wave forms)
Enjoy!

Oh, so I need two ROMs, the patcher and the game! Now I get it.

Luckily I have two MFRs. I'll try it later. Smile

It worked!! I just had to add one step to Guillian's list: configure slot numbers accordingly for the MFRs (slot 1-1 = 85h, slot 2-1 = 86h)

Penguin Adventure with SCC and in R800 is wonderfabuloamazingous! Smile
