NEW OR UPDATED ARCADE CORES

[Darfpga]

Lunch time approaching!

Burger Time VHDL arcade game source code for DE10_lite available here :

https://sourceforge.net/projects/darfpg ... urger_time

Feel free to port to MiST/MiSTer.

[NML32]

thanks, I really like Burger Time.

[Gehstock]

Thank you verry Much

Sound+RGB not testet need Feedback

Perfect !
Thanks to all

Can test tomorrow early in the morning...

Thank you for the Burger Time core. Graphics and sound work as expected and the image is perfectly aligned at 15 kHz.

I can confirm, very nice work!!!

[Gehstock]

OK thanks for feedback

Burnin' rubber FPGA arcade game for DE10_lite available here :
https://sourceforge.net/projects/darfpg ... in_rubber/

As usual feel free to port to MiST/MiSTer.

It seems 2-player mode is broken. After first try on player-1, it switches to player-2 and never switch back to player-1 till the end of game.

Can you describe more: what is wrong ? The display in cocktail mode ? The control button or the number of the player who control the game?

I've changed to non-cocktail mode, 5 lives. So, both players have same screen rotation.
- start the game in 2 player mode
- game played for P1 and switch to P2 upon life lost
- game played for player P2 but remained on P2 upon life lost.
- remains on P2 till all life used where each life used twice.

I see in new core you start to use such constructions:

Code: Select all

	if rising_edge(clock_12) and clock_6 = '1' then 
	...
	end if;

Which is not correct since clock_6 goes to sensitivity list and can act as a clock while it shouldn't. The correct construction should be

Code: Select all

	if rising_edge(clock_12) then
		if clock_6 = '1' then 
		...
		end if;
	end if;

May be this affects the core work?

I've just tested this config : no problem here, toggle player1/player2 is ok after each life lost for each 5 lives.

Thanks for the feedback, I agree the construction isn't good and at least ambiguous and maybe handled differently by different compilers. I must correct this and avoid it in future. I've checked with RTL viewer that clock_6 signal always ends on ENA pin of DFF registers and clock_12 on CLK pin of DFF. Fortunatly compilation complains about clock_6 not being in sensitivity list and clock_6 is never promoted to a clock signal.

Anyway you are absolutely right, thanks again.

Nevertheless I cannot reproduce the problem here so I cannot find a solution. I hope that you are not misleaded by the fact there is no 1UP/2UP blinking and sometime no PLAYERx GET READY screen after the first one. It is the same on Mame, only scores counter increase make the difference between player1 and player2.

ah, you are right. I didn't notice it switches between players seamlessly.

New Core

War of the Bugs

But Same Problem with Fonts like all Galaxian HW Cores

Download on my Github

[Sorgelig]

looks like centipede

[Gehstock]

Yeah, Mist have not yet a Centipede Core

Nice! Will test tomorrow morning!

[Sorgelig]

MiSTer too
What's the problem with Font?

[Gehstock]

the First picture is VGA Output , Font lacks of the first Pixel Line. RGB is ok(second Picture)

scandoubler eats first pixel. If it's hard to adjust scandoubler, then you can deactivate hblank in the core one pixel earlier.

[Gehstock]

Ok Thanks will Check

[Sorgelig]

Or, add intermediate registers for RGB data assigned by pixel clock. And it will shift the whole picture one pixel to the right.
You need to do this before scandoubler.

somethig like:

Code: Select all

reg [..] Rd,Gd,Bd
always @(posedge pixclk) begin
	{Rd,Gd,Bd} <= {R,G,B};
end

Rd,Gd,Bd -> send to scandoubler.

Thank you

Sligthly better Fonts on Galaxian HW Cores and Gameboy Update

[DrOG]

Hi!

Tested the War of Bugs and Azurian core briefly, still odd-looking, but better over VGA (see attachments).
