You may be interested in a new IPS patch for beloved Konami classic Gradius (a.k.a. Nemesis), created by Japanese MSX enthusiast SHALOM. When applied, it modifies the graphics to make the sprites, surroundings and font look more like their incarnations on other home platforms and arcade machines.

Wow, this is awesome!!!

May it work with SCC version of Gradius?

How can I modify graphics of others Konami roms?

I wondered the same thing. Is there an IPS patch to get SCC music for 'normal' Gradius?
In that case, applying both patches to the same ROM might work. Extra awesomeness. Smile
Because, the SCC Gradius is on disk, right?

Too bad that both patches seem to confict with eachother. Sad
But man, now it reminds me, those SCC versions of the Gradius music are sooooo ridiculousy cool. Smile

By the way, some kind of tutorial on how we can modify ROMs ourselves would indeed be very nice!

IIRC you can extract the tile data and sprite data quite easily (remember ripping them to take a look at them.

I think even some of the standard tile editor form the other platforms can work.

From the other platforms? then what if the color can't be changed on the tiles? I mean, to draw with SC2 colors.

How I insert my graphics later on the rom?

If the graphics aren't compressed, it's just a matter of overwritting them at the same file offset.

SLotman, logical as that may sound, some guys still won't have a clue how to do it. I know because I'm one of those. Smile

Please someboy explain all the steps clearly and the programs to do it.

@SHALOM: Well done!!!

Lets open a new topic to show to the people to change graphics of Maze Of Galious, for example.
Please someboy explain all the steps clearly and the programs to do it.

There is no general approach. To do this. But here is what to do if you want to try:

1) Locate the gfx data in ROM (sprites, tile pattern, tile colors).
There are 2 ways. to do this: a) lookup the VRAM updates in the code to resolve the addresses in ROM. b) brute force by displaying the ROM contents as MSX graphics (e.g. simple Qbasic, blitz basic program will do).

2) Export the graphics found in a format you are comfortable with (bmp. polka, etc)

3) change the graphics as you like.

4) Import the changes back (and create an IPS patch).

Remember that this method can only be used to update the patterns not the layout of the game screen, NPC's, sprite colors and levels.
Changing the gfx seems easy to do. But it takes skills to make it look better than the original.

Anyway. The most fun part is doing this yourself. Wink

Good evening, MSX freaks. ^^
Now is 20:20, Sept. 7 in Japan Yokohama.

This project began from a few replacement about 10 years ago.
It started with being inspired Kashion's patch. (http://hlc6502.web.fc2.com/gra_ac.htm)
I experienced programmers, It was advanced dramatically 3 years ago.
I wrote a own C# application that analyzed the graphics compress processing.
I got a knowledge of Z80 and MSX-systems from faith brother.
And now I have completed a reverse engineering about 70%.

About SCC Version
Perhaps the binary can be rewritten. However, it is necessary to analyze the version of SCC.
SCC version has built of the new Sound Driver. Therefore, there are some design changes of coding.
Unfortunately, I do not have time for analysis... I wait expecting a challenger's appearance! ^^

Reason of non SCC
Konami's software is intended that the minimum system configuration.
I want to respect the design of Konami MSX team.

It is part of my private life. So, please wait patiently. :-)
See you soon! ^^:murdock:
