Arcade cores

[hyperterminal]

It's possible, but it will require every core modification specific to each core.
I'm not going to another round of 50 cores modification.

This is understandable. Most people play with the default dip switch settings anyway, as these are the only settings accepted for high score competitions. Maybe you can update just some of the more popular cores when you have some spare time. But this feature is definately not top priority.

Talking about Arcade cores: Have you considered to further improve the NES core so that (partial) support for the Nintendo VS Unisystem is added?

A first and easy step (as you already have a palette selection option) would be to add the Arcade palettes of the different VS PPUs.

They can be downloaded from here:

Here is a test rom that might help with the development:

I would prefer someone will add modifications and provide the pull request to me.
I cannot handle everything myself.

Hopefully this is in the correct section:

I have robotron working in lite mode (see attached pic). I was just wondering if anyone else was working on this, it has the roms embedded in the code and my next task would be to remove this and read from the SD card. This may take some time.
I have not written code for FPGA's before and as my user name suggests I am retired. With the few brain cells left from my misspent youth I am having fun tinkering, although the smd soldering was a challenge. If some one else is working to get this going I can sit back and wait.

I remember something has been missed to create robotron arcade. Probably audio board.
So far, no one working on this core.
The pic is missing probably because you are trial user currently with limited rights.

So, you've made this arcade fully working (beside the lite mode and embedded ROM)?

As for age - i think many retro devs are 40+ already

ROBOTRON
Nearly working - I used the sound and cpu from defender together with the rom and ram code. The robotron blitter uses 4 bit so had to split the ram.
The embedded rom code was removed and now loads from SD. I am now down to less than 100 warnings.

ISSUE On loading the lite sof the system hangs for about 30 seconds - reboots then everything appears OK. The rbf does not work.

I have uploaded the code to github under davewoo999 / Robotron-for-MiSTer if anyone is interested. keys are a bit awkward but I set them up for testing. I added the joystick (2 of them) code but have no joystick to test. Instructions in the Readme.txt

There are probably timing issues as Joust will only run for around 3 levels then crashes. (work in progress as I believe they use the same core)

[oldgit]

Space Invaders
I have uploaded to github space invaders. Lite version and HDMI only, the rbf works. I could not get a build on the full version as it just hangs at 30%.
Untested joystick support ( must get a joystick).
2 player support and updated sounds.

Hope this is the correct forum but I'm having problems with display output with a bunch of Arcade Cores;

I don't get any output (screen goes into standby) on (I've tried other but can't remember there names so won't include them)
Galaga
Bomb Jack

Alibaba on the other hand works fine

I'm using the latest MiSTer firmware with an 8GB SD Card, the ROMs all created without error. I don't have the IO board so can only test via HDMI and I've tried this on a monitor and a TV with the same symptoms. I assume I'm doing something wrong and any help would be appreciated.

No problems here with your mentioned cores, latest MISTer file.

Please check your mister.ini in config folder.

Try vsync_adjust=1 or 0
Also try a lower resolution: video_mode=0

If this doesn't help please check if you have the correct mame set roms.

Hi, thanks for the tips - it was the romset that was the issue. All working now. Thanks again.

but i found original Pacman core doesn't emulate 8 sprites as it should. It emulates only 6 (as Pengo).

original pacman hardware will only draw 6 sprites - many of the bootlegs will support 8, one of the cases where the bootlegs are more flexible than the real thing!

it was very old message. Many things have been changed since that time.

Hi,

I used to play the Japanes version of Donkey Kong. dkonj.zip. Is it posible to compile this particular rom set?

TNX!

[funkycochise]

I'm just pointing out something I noticed with this build of DK. I'm not reporting a bug or an issue.
In this version the game starts with 6 lives, the default is usually 3 lives.

Per DK wiki:
The player typically receives three lives with a bonus awarded for the first 7,000 points, although this can be modified via the game's built-in DIP switches.

Today i got Quartus Prime 17.1 running

Attached Donkey Kong with 3 Lives and 7000 Bonus default. Now i have to struggle with the rest

hi, could you please explain what you have change ? maybe provide your modified source file(s) ?
got also my first Quartus build work.

sorry for double post.
I found the dip switch settings in top file.

[oldgit]

Space Invaders
I have updated the files in https://github.com/davewoo999/Space-Invaders-for-MiSTer
The rbf is still in lite version only ( No full version of Quartus). The source files will compile on the full version to use the scaler.
Changes - I noticed just after updating that I changed the clock files to 40 20 10 and 5 from the original so it does run slightly faster than original.
OSD options to change some of the dip switches.
VGA screen shows the original sideways screen.

tested space invaders .
works fine, some small details, if you reset the core some garbage appears in the borders.
Joystick Works but only direction and fire , not coin ,player1 or player2
thanks for your work.

thanks for your work.

Thanks for testing - The non working keys - for some reason I used joystick5 for fire and 8 for the coin/start. I can change these to 4 5 and 6 like most other arcade cores.
I have a problem with updating the core as whilst working on it today I left it running and had lunch. On return the hdmi screen was blank and the vga screen comes on and off every 2 seconds. It even does this on downloading the core from github. Not sure what's going on but will attempt to get to the bottom of it when back from Hols.

[funkycochise]

I’ve tested space invaders. It’s really working great. But only through the hdmi.
on the CGA video output through gpio port, I don’t have any picture.

thanks for sharing.

Scramble arcade core - game should have separate buttons for forward-firing weapon and second for bombs like as original.

you are right.
fixed.

This weekend I noticed that pacman core has wrong color palette. The colors are the one of pacplus.



I suspected the rom to be the responsible but it wasn’t.
I changed the content of 2 files in ROM folder of the source project :
PROM4 and PROM7 that are the content of proms 4a and 7f. The right contents are the same as mspacman ones.

With the right content, I could get the right colors.



Could you please change that and build the core in full version ?
Thank you.

Edit : I did a repository (I don't know how to create pull request, I'll dig that way), a lite version in release is available in output for those who want to test.
https://github.com/funkycochise/
Edit 2 : modifications are now in master project, new release to come.

[AndrewSisk]

Scramble has no sound for me,did I do a bad Rom build?

[yarko]

Sorgelig - thank You very much for Scramble fix. If you would be very bored Bagman arcade core is in French language only. In MAME emulator language can be changed with "DIP Switch" for English/French like in real arcade cabinet. Maybe similar option in F12 menu is possible?

[oldgit]

Space Invaders
I have updated the files in https://github.com/davewoo999/Space-Invaders-for-MiSTer
The problem with the screen should be fixed and joystick should work for player 1 and 2
The OSD now has the option to change the overlay colours.
New rbf in release folder

I shall now get back to trying to get robotron / joust working and get myself a joystick so I can actual test these cores.

[albconde]

Tested and Works great, I only miss the orientation option .
Sorgelig , with this core and TI99 core that are not in the Mister's code repository,It may also be a good idea to put a link in the wiki ?
