@Dink: the select stage cheat doesn't work for turtles in time? but there's no problem with the rest of them.

I've noticed a strange bug with FBN on Retroarch. When I load legend of hero Tonma (jap version, lohtj.zip), I got the World version ??
The rom is correct because when I load the same lohtj.zip with mame core (current), I got the japan version, so I think FBN is reponsible ?
Another question, why there are no warning japan copyright text at start for Irem M72 roms ? (R-Type is the only exception)

The loaded romset is clearly the japan version. Why do you think it is actually the world version ?

I didn't hook up the protection MCU yet for IREM M72, and its this mcu which stuffs the warning into vram.  This mcu isn't very important, which is why emulating it has a really low priority.  It doesn't control game logic, it just gets the game to boot and a couple tiny other things & that's it.  The "simulation/hack" which we use now does that just fine.

Difficulty is lower on the japan version. There are more enemies in the world revision (which is very rare because most of the western arcade revision have lower difficulty, but not for Tonma).
I've made 2 replays with both counter stop (on pcb and on mame), so I know really well both versions : https://www.youtube.com/playlist?list=PLqZUIyT8c0OImPBeGJhGJcfClWc0ZYg6w
I recognise that the differences between the two versions are subtle for the average player.
Also, why I can see the differences when I load the same jap rom with mame ? (and not with FBN)

Can you please tell me exactly how - like, the easiest way to tell the differences?  I loaded up loht and lohtj with mame and played the games side-by-side and couldn't notice a difference.  Once I can do this, I will be able to look into the problem in fbneo :)

I just tried Ninja Emaki, and I'm quite confused. Just moving around (using a keyboard) will randomly teleport you from time to time.
Is that supposed to happen? Or maybe the game reacts poorly to direction inputs that were not possible on the original cabinet? Thank you.

Probably the usual simultaneously pressed down opposite directions bug.
It's not happening with a gamepad/joystick.

Hi Stifu,
As Tatsuya79 said, some games don't like opposing directions pressed (even accidentally).  Driver has been fixed, thanks for your bug report :)

p.s. did you see this update - added the color filter to Navarone a few weeks back :)

best regards,

Yes, I did, thank you!
I just thought it'd be bad to spam thank you comments every time (and so I just use that "applaud" link thing thinking maybe you get a notification or something), but I am grateful for all of your work.

I must admit it's not easy to see if you're lambda Tonma player. All the differences during the first 4 stages are very subtles.
In stage 1, the respawn vampire enemies is higher in world version (maybe 20/30% faster than the jap version)
In stage 2, at start, all the first enemies shoot at you quicker and their bullets are faster. The boss shoot also more bullets.
In stage 3 & 4, there are little more enemies but it's not easy to see. (both boss seems to have identical pattern)
In stage 5, enemies (blue soldiers) respawn much more faster and they're more resistant (boss have identical pattern)
In stage 6, there are more ghosts and flying skeletons. The boss pattern is more difficult. You can easly see it.
In Final boss stage 7, There are 3 big birds (for every pattern) in world revision while there are only 2 in Japan version.
I will try to study other differences between both version.
I share here 2 run on both version with mame (INP file to playback) to help you. I can made video if you want ?

Thanks & best regards !!
