Mame 2003 Question regarding : Lucky and Wild

escc1986

After reading the doc about the cheats

I still don't understand, could you explain it to me in more simple terms , I apologize if I don't understand , i have never used
fb nero and everything sounds so complicated to me , I guess because I'm not use to using it

@escc1986 Bear with me, i never use cheat code but i'll try to explain it to the best of my abilities :

the first method involves using Quick Menu > Cheats to input cheat codes directly into the game's memory, while that's the "official way" to use cheat code in a libretro core, i've seen a lot of people saying it's totally unintuitive, that's why i implemented the second method recently
the second method involves creating a cheat file in your BIOS/fbneo/cheats/ folder, here is a pack of cheat files for FBNeo, i'll also give an example of how to convert a mame2003+ cheat into a FBNeo one.

Look at the the mame2003+ cheat file at https://raw.githubusercontent.com/libretro/mame2003-plus-libretro/master/metadata/cheat.dat, you can see the following code for luckywld :

luckywld:0:107156:75:000:Infinite Time
luckywld:0:107157:30:500:Infinite Time (2/2)

Those 2 lines are for the same infinite time cheat code, the first one means you are inserting 0x75 at address 0x107156, the second one means you are inserting 0x30 at address 0x107157

To turn this into a FBNeo cheat code, you'll first need to create a luckywld.ini in the cheats folder if it doesn't already exist, then copy the following code in it

cheat "Infinite Time"
default 0
0 "Disabled"
1 "Enabled", 0, 0x107156, 0x75, 0, 0x107157, 0x30

The 1st line represents the name of the cheat code
The 2nd line represent its default value
The 3rd line is the first choice for this cheat code, here it's "disabled" for value 0 (which is the default from 2nd line)
The 4th line is the second choice for this cheat code, here it's "enabled" for value 1, see how the numbers after that are actually the same as mame2003+ ?

After that, when you enter Quick Menu > Options, you'll see your cheat in the list

@escc1986 mame2003 and mame2003-plus are now fixed to play luckywld. Precalibrated. All you have to do is update the emulator from source to get the new update. Then delete the luckywld.cfg and luckywld.nv files. The new update will auto generate these files with the corrections when you relaunch the game.

There's still a small graphics glitch I'm going to look into next but the games fully playable.

@BuZz fwiw, i just committed a bunch of fbneo cheat files at https://github.com/finalburnneo/FBNeo-cheats, maybe you'll be interested in adding those to your fbneo build script.

@barbudreadmon

Thank you very much for the consideration for trying to explain to me the cheats method , also very nice of you to provide me the cheats files for the FBNero, Thank you

It made much more clear sense to me me explaining how to use the codes

As for making mame 2003 codes into FBNero codes is very helpful , a little hard for me to understand but it does make sense and I'm sure I will get it down soon :)

Thank you barbudreadmon

No problem, it might be tricky on a limited controller but I was able to use a PS2 style controller with a few different control options. I used the dpad to aim, circle and square to steer, cross for gas and r1 to shoot. You could also use the dual analog sticks to aim and steer. I don't brake so didn't worry about that.

Just enter the mame menu, select "input this game" and set the controls however you'd like.

Aim
Lightgun x
Lightgun y

Dial
Steering wheel

P1 button 1
Shoot

Pedal 1
Gas

Pedal 2
Brake

Thank you !!!!

@mahoneyt944

Thanks again for the game !!!!!

Just finished the game now

Wow !!! What a fun game

Always saw this game at my local arcade growing up but was always to intimidated to pursue to play it lol

Glad to try it

thanks to you and the others who lend a hand was able to help and I was finally was able to play this game

Thanks again for this childhood memory that I wanted to try and never got a chance to when I was young !!!! ;)

@mahoneyt944 First of all. Thank you for all your efforts!
I'm having trouble making the crosshair work with the gpio arcade buttons. Dial, shoot and pedal work ok but the crosshair of the game does not move, only the mame one which is white. Any suggestions? I remember being able to play this on recalbox some years ago

mahoneyt944

@Ogroto if you're trying to play lucky and wild you'll need to update the mame2003-plus or mame2003 from source to get the new update (which ever you use). Then navigate to your save directory and delete your old luckywld.nv and luckywld.cfg

The new update should auto create these files when you launch the game. The nv file contains the lightgun calibration. And the cfg has the fixed controls.

My nv file directory is located:
/roms/arcade/mame2003-plus/nvram/luckywld.nv

My cfg file directory is located:
/roms/arcade/mame2003-plus/cfg/luckywld.cfg

@mahoneyt944 Thx! i will try it soon and report back

Hi Mahoney

Just curious not sure if it works but

Any way of getting " Rail Chase" (Rail Shooter game) to work on MAME2003

I knew that game was unable to work on the Pi from reports from others

I actually tested the game on the " WIP" mame2016 and it worked and I completed the game with outany issues .. just was curious if you could get Rail Chase on 2003 ?

mahoneyt944

@escc1986 it might be possible but currently not implemented.

escc1986

@mahoneyt944

Thank you for getting back to me

Also Appreciate you letting me know

Would be nice to see this game in the future

If you happen to ever get time to check out or make an update with this game please let me know

Thank you once again

Please forgive me for replying in an older topic, but I just had to thank barbudreadmon for his explanation on "how to use cheat codes with FBneo." I've been on youtube, tons of forums and could only get .cht's to work but not the .ini files. Some very smart folks here....... Thank you so much :D.
