It sounds much better with low-pass on. Sweet. I tried some of my favorite games and none of them had any issues with it.

Barbudreadmon, could you confirm the setting name for libretro? I looked around but could not find it. Thanks.

LowPass Filter, it's right below FM Interpolation. I added it only recently (maybe 2 weeks ago ?) so make sure your core is up-to-date.

Hi! I have the sound option always activated. In Neo Geo games, CPS1, CPS2 and CPS3 it does not give any problem. In Tetris (set 1) (atetris), for example, just at the end of the level or at the end of a group of levels the sound degrades a lot. It also happens in Operation Wolf (World, set 1) when there are a lot of explosions. I will try more old games, and if I find something I will tell you about it. Greetings.

Hi Neildark,
Thanks, that's a big help - Atari Tetris and Operation Wolf have been fixed

It's not very important, but I think there is a bug in the sound when inserting the first credit in CONTRA game.

When you insert the first credit in mame, it gives a particular sound, but in FBN the sound sounds like choppy or different. I don't mean the second credit inserted immediately after the first one (which the sound is longer), but the first one.

I have tested it in mame version 220 (beyond that version, some games slow down for me.

Greetings.

I have made a recording by inserting the first coin, it will play after a part of the intro music of the game finishes. Maybe you have to give it volume since I recorded it with the phone.

Pelucon8, I think the problem is solved, please give it a try:)

Now you can hear it very well. Thanks for fixing it, dink.

Slightly Complex Cheats

Rarely, some games use a linked list for the player & enemies, and the place the player's status etc. is held in memory always changes, but there is a location that points to this list that never changes.  In the past FBN ignored these cheats, but as of today, we support them (in cheat.dat format!)

For example:
rdft* - Raiden Fighters 1/2 "Invincibility"
androdun - Andro Dunos "Invincibility"
dreamwld - Dream World "Invincibility"
There's a couple more, but there aren't many

Even if you're not a fan of using cheats, they have their uses - for example: they help us debug the emulation, take screenshots and other such technical things.

My cheat.dat (attached file) is based on Pugsy's cheat.dat for MAME 0.126, found here: http://cheat.retrogames.com/mame_downloads.htm
With a couple updated entries.

The invincibility trick doesn't work in the "shinobi" and "shadow dancer" games. All other cheats, in both games, work perfectly. The cheat.dat that I use is the "cheat_dink_march9 -2021"

Greetings.

I forgot, I use this emulator update:

[dink]

Pelucon8,
The invincible cheat should be OK for Shinobi and Shadow Dancer now, please give it a try.  Do let me know if any new problems spring up with cheats, because the fix for this specific problem needs a bit of testing

best regards,

[Pelucon8]

@dink

Now it works! Thank you very much 

If I find any other cheat that doesn't work I will inform you here.

Regards

[dink]

Pelucon8, excellent - thanks

[dink]

Hooked up buffering + timer to the YM2151 in CPS1 games (the games without QSound).
If you notice any weirdness with CPS1 games after this update, please let me know!

I added GameGenie code support to NES emulation, one can easily add gamegenie codes using your favorite text editor...

Cheat files for Contra and SuperC were posted over here: https://neo-source.com/index.php?topic=139.msg32107#msg32107

If you'd like to make your own cheat files, just paste this into a text file, name it nes_ROMNAME.ini, and put the file in support/cheats.

Code: [Select]

cheat "Description of Cheat"
0 "Disabled"
1 "Enabled", "CODE"

Let's say you want to add the Infinite Lives code for Super Mario Bros, and the gamegenie code is SXIOPO

Paste this into a text file named nes_smb.ini:

Code: [Select]

cheat "Infinite Lives"
0 "Disabled"
1 "Enabled", "SXIOPO"

If you come across a GameGenie cheat that uses more than 1 code, for example:
Always keep Fireflower power-up, codes: OZTLLX + AATLGZ + SZLIVO
do it like this:

Code: [Select]

cheat "Always keep FireFlower Power!"
0 "Disabled"
1 "Enabled", "OZTLLX", "AATLGZ", "SZLIVO"

TIPS:
grab the latest exe at the usual place before trying this
After loading the game press Ctrl+F1 or menu "Misc -> Enable Cheats" to bring up the list.
https://github.com/finalburnneo/FBNeo-WIP-Storage-Facility/releases/tag/appveyor-build
If you don't know which exe to get, get fbn-win32-gcc.7z

bye for now, have fun!

Two small issues with "Operation Thunderbolt":

1) The FB crosshairs are a bit off, a bit too low, evidenced when you pick the laser sights.

2) The image of the airplane at the end of the game is duplicated. I think the same happens in MAME.

The image of the airplane at the end of the game is duplicated.

Thanks for the report, it would help if you could provide a savestate.
