Hello,

just a simple question (not very important, but Im still interested)
I have a disk with parodius for 128kb (and it supports scc)
the loader (parodius.bas) does this:

1 poke-609,202:if peek(&hf677)=128thenmaxfiles=0:clear20oke&he100,0oke&hf677,&he1:run"parodius.bas
2 for a%=1to5:bload"parodius."+hex$(a%),r:next
3 bload"parodius.6":defusr=peek(64702!)+256*peek(64704!):fora=1to3000:next:a=usr(0)

parts of this code i understand
what I dont understand is line 3.... what happens there?

And the actual questio I have is:

This game works with scc in slot 2.
Is it possible to change a bit in this code so it works with scc in slot 1?

First command loads "parodius.6" file. Next it defines start address of file as execute address (here must be a typo. the first address should be 64703) FOR command is used to wait for a while to let older MSX machines to stop disk drive from spinning. Then program starts the ML code.

This code has no anything to do with the fact, that SCC needs to be inserted to slot 1. To change that, you should study the ML code. I would start looking from the "parodius.6" file as that is the loader and propably has the needed support routines for this crack.

I added to it SCC slot detection routine, but it seems I did that bad, because patching didn't help.
Maybe setting the slot number is done in more than one place.

It can be very comfortable to have all the Konami carts you own also startable from your MSX harddisk. No need to get them out of the boxes and loads almost instantly

It's even more comfortable to have all the Konami carts on your HD even when you don't actually own all the Konami carts... Hence... No asking for stuff on this site please...

if you are a proud owner of a original KONAMI why do you want to play it from hd?

if you have the original game and want a usable romfile to load from hdd DUMP your game to a rom file then play it with loadrom.... Megamu... from HDD

It is easier to do it using a menu program and selecting a key rather than inserting it into the MSX.
To play from HDD/CF
1. Switch on MSX
2. Automenu program loads, press keys and/or use mouse
3. Start playing

To use original cartridge
1. Retrieve game from shelf/storage
2. Insert into MSX
3. Switch on MSX
4. Start playing
5. When finished, switch off MSX
6. Put game back into storage

Maybe the next poll could be something like, If you have the original ROM's do you load the image from HDD/CF? or do you get it out of the box and play ?

It is more convienent to do the former method!

Interestly, we know the MRC policy about pirated software, which is commendable. However, why does the downbload section include a ROM to COM converter? A program to load ROM images into a SD-Snatcher sound cartridge? A ROM extractor? and a MegaROM splitter?

The ROM to COM program could be used legally, however why would you need to load a legal copy of a ROM image into a SD -Snatcher cartridge? Why would you want to want to split your own megaROM image?

Maybe these sort of programs, which seem to indicate that MRC condone piracy should be removed from the download section?

Ok espicially after your first paragraph about the conveniance side of not using the original games on your msx, these question must be rethorical or flame-bait. But I'll answer anyway

wel it is easier to have all your SCC games as romfiles on your HD.
You extract them using the given tools and when you want to play them (with SCC sound ofcourse) you load them in the SD-Snatcher cartridge and play them, otherwise you'ld have to install a cracked game on your HD instead of your own nicely extracted game.
And the SCC cartridge can remain in your MSX indefinitely, since it doesn't contain a game normally and can be used for SCC(+) demo's.

And that last remark doesn't make sence, simply because the tools allow you to excercise your rights as legal owner of the cartridge.

Sorry! I was thinking of the flash megaRAM's that you can get and the ESE MegaRAM which allow you to load the images and go to another machine and use them!
