How to completely disable CRC checking.

SRC/BURNER/BZIP.CPP

find this:

Code: [Select]

if (List[nFind].nLen == ri.nLen) {
if (ri.nCrc) { // If we know the CRC
if (List[nFind].nCrc != ri.nCrc) { // Length okay, but CRC wrong
RomFind[i].nState = 2;
}
}
replace with this:

Code: [Select]

if (List[nFind].nLen == ri.nLen) {
if (ri.nCrc) { // If we know the CRC
if (List[nFind].nCrc != ri.nCrc) { // Length okay, but CRC wrong
RomFind[i].nState = [color=red]1; // Changed 2 to 1[/color]
}
}

Why not adding a check box in order to enable/disable the No CRC check :

in src\burner\win32\resource.h

Find:

Code: [Select]

#define IDC_SEL_ASCIIONLY 20063
ADD this after

Code: [Select]

#define IDC_SEL_NOCRC 20130
------

in src\burner\win32\sel.cpp

Find:

Code: [Select]

#define ASCIIONLY (1 << 19)
ADD this after

Code: [Select]

#define NOCRC (1 << 20)
Find:

Code: [Select]

CheckDlgButton(hSelDlg, IDC_SEL_ASCIIONLY, nLoadMenuShowX & ASCIIONLY ? BST_CHECKED : BST_UNCHECKED);
ADD this after

Code: [Select]

CheckDlgButton(hSelDlg, IDC_SEL_NOCRC, nLoadMenuShowX & NOCRC ? BST_CHECKED : BST_UNCHECKED);
Find:

Code: [Select]

case IDC_SEL_ASCIIONLY:
nLoadMenuShowX ^= ASCIIONLY;
RebuildEverything();
break;
ADD this after

Code: [Select]

case IDC_SEL_NOCRC:
nLoadMenuShowX ^= NOCRC;
bRescanRoms = true; //update the game selection screen
CreateROMInfo();
RebuildEverything();
break;
------

in src\burner\bzip.cpp

Find:

Code: [Select]

if (List[nFind].nLen == ri.nLen) {
if (ri.nCrc) { // If we know the CRC
if (List[nFind].nCrc != ri.nCrc) { // Length okay, but CRC wrong
RomFind[i].nState = 2;
}
}
REPLACE with this

Code: [Select]

if (List[nFind].nLen == ri.nLen) {
if (ri.nCrc) { // If we know the CRC
if (List[nFind].nCrc != ri.nCrc) { // Length okay, but CRC wrong
if (nLoadMenuShowX & NOCRC) {
RomFind[i].nState = 1;
} else {
RomFind[i].nState = 2;
}
}
}
------

in src\burner\win32\app.rc

Find:

Code: [Select]

CONTROL "Use only Latin text",IDC_SEL_ASCIIONLY,"Button", BS_AUTOCHECKBOX | WS_TABSTOP,76,241,100,14
REPLACE with this

Code: [Select]

CONTROL "Use only Latin text",IDC_SEL_ASCIIONLY,"Button", BS_AUTOCHECKBOX | WS_TABSTOP,76,241,80,14
CONTROL "No CRC check",IDC_SEL_NOCRC,"Button", BS_AUTOCHECKBOX | WS_TABSTOP,156,241,60,14
Now you have the choice to enable or disable the CRC check.

ps :

Code: [Select]

case IDC_SEL_NOCRC:
nLoadMenuShowX ^= NOCRC;
bRescanRoms = true; //update the game selection screen
CreateROMInfo();
RebuildEverything();
break;
bRescanRoms = true;
CreateROMInfo();

this rescans the romset in order to update the icon in front of games that are bad (wrong CRC), so if the NO CRC option is enabled, it removes the red icon in front of the games that have bad crc....



[EDIT]

hmmm, the "code" feature of the forum do not like tabulation

#define IDC_SEL_ASCIIONLY         20063

[Badablek]

what about if we disable the size check with the crc check? sometimes we have different crcs due to a size mismatch...

note: this code considers that you have the disable crc check with checkbox option

ooops....it seems this feature was already done by someone else 

BTW I learn to write some code, even if it was already done 

[Shoometsu]

yeah , the disble crc and the checkbox for this where developed for someone else, I just changed the crc check to ignore a size mismatch error too

if anoter one have done this before I don't know, because I've never seen this before, so I've posted it (yeah, I don't browse by chinese forums,  I won't understand anything)

Hi,

Changelog of FBA-xxx Pro 1.12

- Patched out HW test in Neo-Geo games. (removes ugly green screen on boot) (by iq_132)

Any chance to post the trick to disable the Neogeo Hardware Test ? It sounds very interesting ^_^

Hi IQ is there a Mame conversion for this ? hehe

Yup, that's exactly what it does.

NeoGeo Music Changer Extra Feature

Note: Just changes Music on some NeoGeo games, If somebody manage to get more games to change the music somehow, I will apreciate the help =) , this code works kinda like WinKawaks because it have the same problems with neogeo music.

Well thats it !! If you want to test something after that, Kof98 is one of the games that works with the music changer code

I hope this code turns out to be useful for some of you ^^

SeeYaa!!


PS: Well this is all for now lol, have to get a sleep ^^..Take Care all!

[CaptainCPS]

Here is a little pic of the code posted before working =)...

I forgot to mention how to use the feature hehe...

PAGEUP -> Next Track
PAGEDOWN - > Previous Track
HOME -> Reset to 0x0720 Default Track

SeeYaa!

[CaptainCPS]

Posting here to let you know I managed to Change CPS-1 Music Tracks too!!  (needs a little adjustments because some sounds keep playing when there are no more music tracks)

Im gonna post the code soon, Im trying to change CPS-2 music tracks too, but QSound seems to be a little more complicated 

SeeYaa!!

[iq_132]

Excellent   Here's some code to parse Nebula track list files if you're interested.
I haven't tested it since I converted it to work in unicode, but it should work fine.
I'd be sweet to see it display the track title & number while you're playing them
