31ee705dba lohtb2: Improved mcu emulation
* The whole startup cycle now works. No more timeouts and erratic behavior.
* lohtb2 will however not display the "Warning" screen due to a priority issue. With color/attribute of 0x80 in videoram at 0xd0000 and 0xd8000, videoram at 0xd80000 will be displayed. Some tilemap guru has to look into this.

493ccba85f New clone: D2K Jumpman returns
- emulates Braze Technologies addon board
- eeprom hooked up
- implemented bank switching

I am still unsure about whether this should be added or not.
Interestingly, D2K shows a "(C) 1981 Nintendo" copyright message.
Still, it is actively marketed. 
Putting this up for discussion again.

1b7cfe0da2 Another driver from Grull Osgo.
Ruleta RE-900 from Entretenimientos GEMINI.

Is a roulette game based on i8051 and TMS9928, that has a phisical roulette with leds simulating the ball.
Game is working properly with full sound support.
Need better inputs implementation, leds, external artwork for the roulette and technical notes (I'm taking care of them).
If someone want to give a try, turn the operator key to allow enter credits.

Subject: Sound Support for Cosmic Alien

Hello,

I own a cosmic alien PCB and so I thought it would be a good idea to add
sound support
to this game by changing the corresponding driver ("drivers\cosmic.c").
I also have recorded the different sound effects as wave - files.

I have attached two files to this mail. The file "cosmica.zip" contains
the samples
(so it can be simply copied to the "samples" folder) and
the other one "cosmica_diff.zip" contain the "diff" file taken against
the 0128 sources.
So you can check it and maybe you want to implement the changes in a
further release?

best regards

the wrong tags were used for maketrax when indexed inputs were converted to tagged ones (0.125u7): input 2 was 'dsw1' but 'in1' was used. probably a mistake I made. sorry.

Subject: 65c02 core bugfix
Hi,

This patch fixes a subtle bug in the 65c02 emulation where the result of
the BIT instruction  differs on the 65c02 (from the 6502), when executed
in immediate mode.

Cheers,

Phill.
