278 will require some non-trivial changes in order to adapt to the new audio infrastructure. Don't panic, I'll do it. However, I have some very important personal matters that I need to attend at the moment, that will take this whole month yet probably, so I won't be releasing more versions until I have some time to focus.

Hi geecab,

I switched on the high score table on my set up last night (only spotted that feature when I was watching through some of your videos. Anyway, when I was pressing my accelerator pedal to select a letter, it wasn’t working. I have to have my pedal selected as inverted in the game options to get it working in game. Just thought I’d mention it so you can add it to the fix list. Cheers!

Hi GPForverer2024!

Whoops! I've found a bug in in my scoreboard_to_revcounter util (It was the reason for the strange RPMs I was seeing when I'd set my revcounter cylinder switch to 3,5,6 or 8-cylinder).

I actually think my KET105 revcounter is a good bit of kit now. I've modified the big post I wrote on Sunday to paint it in a better light.

I'll upload a new MGPr package in the next few days that has the fix :)

No clue who you bought it from but here's the manual if you're missing that.

A search of "g500 arcade gun" put this as the first result...

Hi arc11,

I think the expression target_pixel_width / float(raw_font_pixel_height) / options().font_rows()
should probably be target_pixel_width / float(raw_font_pixel_width) / options().font_rows()

I'd say the expression in GroovyMAME is correct, because it's calculating the scale based on the total rows. It'd be of help to know in which exact situation (resolution) the screen is unreadable.

The font scaling changes were thoroughly tested to ensure integer scaling was correct for fonts in all situations. To achieve the expecte results you're supposed to use the uismall font on the ui, instead of the standard default.

I don't know of any workaround, anyway if I remember correctly Calamity said GM users should not use the native mame front-end at all. Either command line or third party frontend.


In a completely different matter :
I have a general question about the game selection menu (native mame frontend).
Is there a way to set the resolution ?
Because I have a NAC cabinet with MS9-29 chassis with auto switching between the 24k and 15k mode.
And each time I enter this menu and run a game the mecanical relay that switches from 15k to 24k mode toggles several time each time I enter/exit the menu.

It's not very good for the longevity of this device.

Is there a way to avoid this ? If I add the -resolution AxB@C when launching groovymame, it no longer toggles, but the switchres doesn't switch to other resolution either...

Thank you
