Thanks for adding it (the Dice Game)... The old IREM coin-ops are always a guarantee of quality!

Daiku no Gensan (dkgensan)
[RetroArch 1.10.0 - FBNeo Core V1.0.0.03]

On the intro cut-scene, there is a thin exposed vertical strip on the right that the black 'mask' does not fully cover.
This glitch is only on the Japanese Daiku no Gensan clone and not on the parent Hammerin' Harry ROM (hharry)

"Bomber Man World / New Dyna Blaster - Global Quest".

This game no longer appears to me in the "Show available" list, however I can select it and play it from the "Show unavailable" list?

any idea what could be going on?

I have the latest version (nightly builds): "update title [happppp] (JacKc029735)".

Regards.

Thanks, @barbudreadmon, the game now appears in the "Show Available" list. 

Now the game that disappeared from the "Show available" list was the "Finalizer - Super Transformation (set 1), but when I clicked on it, it said there was a file missing or something, apparently they updated the rom. But no problem, I downloaded the updated rom and it is already available in the "Show available" list.

Thank you very much for resolving this

YAY!

Fixing age-old emulation bug w/Konami without side-effects!

Before and After pics:

(will be on git tonight pending clean-up)

[Gab75]

I remember well this "old" emulation issue related with the scaling/distortion effects... nice work!

[dink]

Thanks Gab75

Grrr, k053245, the sprite chip used in TMNT2, Asterix, Roller Games, Surprise Attack..  (..a different chip than used by The Simpsons & Bucky)

Using the same fix on this chip eliminated the 1px lines in the Asterix logo animation, but, the problem with TMNT2 (Turtles in Time) zoom'd sprites is a different kind of beast altogether.

Back to the drawing board..

Hello
i remember , i have mentioned about this problem many years ago
it is great to see that fixed
thank you people for your all efforts

[dink]

The fix finally made it in to git, please give it a try - should anything weird come up, say something
It should only affect games using the k053247 sprite chip (bucky, simpsons, xexex and a few others)

@Dink, Excellent work, as far as tmnt (turtles in time) is concerned the issue isn't the sprite zooming, it's the explosion with the foot soldiers..How soon you reckon this and the problem with the asterix screen title will be solved ?

[dink]

Hi the_maq,
Well here's what I found out recently:

Asterix titlescreen: on the PCB as the Asterix logo gets squished, it has a horizontal line through it.  On current emulation (fb, mame), you'll see vertical lines also.  With the new fix I'm working on, it functions just like the PCB.. it's still going to have 1 line for a few frames.

The problem with TMNT2 (turtles in time) is due to an unemulated protection mcu which generates the sprite scaling (to control the sprite size), so most of the sizes are generated algorithmically, but, it's not perfect.  It should be an easy fix though once I get to it.
