It looks like maybe some capacitor array (on the inputs for debouncing?) to allow for a smaller board size. I tried to find some schematics to deduct what it is exactly, but can't find it. Also no board pics as to its name.. what's printed on the board? (The black resistor packs are RA*, but...

This post reserved for future updates.

I have decided to release this in the current state, as i keep postponing it because of time issues, or i get lost in writing more documentation. (My backlog is also insanely full, i need to pick projects carefully.) So here it is: A port from source of NBA Jam TE/SE aka the 5.0 Griffey...

The file is 3.2GB, what site can work for us both?

Free bump since i love that cab, it's the Egret of Woodies with its rotate mechanism :)

Please guys, english @chuckying

There is a write filter enabled, so on each reboot the writes are undone. I'm not sure how it's disabled, probably a service you'll need to disable. but @Niko might be able to explain it better. Some info here: https://www.arcade-projects.com/threads/type-x2-pc-build.3481/post-47393 Disable EWF...

I see differences in the way mame handles it and the screen is cut off at the bottom. .if ntsc endvblnk .equ 13h ;scan line to end vertical blanking hsint .equ 108+endvblnk ;half screen eosint .equ 229+endvblnk ;end of screen dirq2int...

I'll try to explain what happens here since the roms are testing bad. What you are seeing is 'correct' for bad rom data. As the game boots it runs the diag code from program roms (which are green.) and shows the test screen with font data in the program roms. (So we know that access to that part...

That sounds to me like a problem with adressing rom space. From my recompiling this game, the gfx used in diag mode (the font, line bars etc.) are all inside the program rom. None of this diagfont is in GFX space area. This seems to point to the PAL. You can use the 8M version in a PAL chip...

First you need to sort out the button issue. For the buttons, retropie (the front end) handles everything. It then passes that along to retroarch/emulator cores. So i advise against remapping anything 'inside' the libretro cores like Mame / FBNeo. You want to remap for a game? (In my case...

In these menus he goes to settings with start, then we have menu resolution and type d'ecran (monitor type) there as settings etc. View: https://youtu.be/KzarPC2KAtg?t=1294 Check the timestamped bit.

You likely have 2 grounds on the edge of the jamma connector, and using 6 button option has this chinese standard. Use a wireless keyboard to re-do the button mapping. The OS thinks you have a button pressed constantly. (coin or start. i think.) Normally 'select' key doubles as shift, and...

And the label on the square chip?

Looks easy enough if you follow these steps. I like OS4. No idea how the UI will look on recalbox. https://wiki.recalbox.com/en/tutorials/video/crt/recalbox-on-crt-with-scart-dac Edit: On a tri-sync this should be pretty good, you run the UI in 31K and the games in 15k/240P :) See also (he's...

For original TE hardware, the two program roms UG12 & UJ12 should be all that's needed to at least boot the game and enter diag mode. Even the fonts for diag are inside the main program roms. If both the original and rewind roms failed to boot on your TE board, something is wrong. Likely, they...

Enjoy. If you're gonna wipe the existing rom set, please check if it's an undumped version first.

Out of curiousity, where did the package ship from?

Check dip switch block #2 dip 7 "freeze game".. "The few times I managed to start the game (on any of the cabs I own, except one) , there is always a problem with the controls ; It's either the joystick doesn't go down, or the jump button is not responding, the rest works fine." There is a...

I hope this is of use to you :)
