Re: Genesis Core

A lot of the unlicensed (unl) an russian hacks (R) games are not working anymore. what you mean by "anymore" is unclear. I've tried Rockman X3 on several older releases - it doesn't work anywhere. So it's simply never worked. Dump probably is bad or original cart has special protection IC...

Re: Genesis Core

Emulators Exodus and BlastEm also write "decode error". So it seems such unlicensed games do something completely unlicensed.

Use licensed games and your hair will be silky and beautiful :lol: :lol: :lol:

P.S.: if there is technical details about this, then i will look for fix.

Re: FPGA SNES source (srg320)

I have several SNES consoles here. I would happily donate them so you can analyze them, decap chips or whatever. I can send them to Sorgelig or you, whoever you guys want. All the SNES consoles on my collection are yours for free to experiment. I will pay for shipment too. Just PM me and they are y...

Re: FPGA SNES source (srg320)

I plan to use improved SDRAM controller which will provide random access rate equivalent to 10MHz SRAM. Currently it's used only for LHRom mapping and therefore only serves the main CPU. It's definitely enough and more than 3 times faster than CPU needs. But after adding CX4,DSPn,SDD1 will it be eno...

Hello First, sorry for my bad English. Nice to see you here! Do you speak Russian? Big thanks for publishing the source! Several people made SNES cores but only you were brave to publish. So, we are trying to port it to MiSTer and there is some progress already. Since MiSTer board has no SRAM, we n...

Re: Mister Gameboy core

According to info i found the Horizontal freq of original Gameboy is about 9.6KHz. It's not compatible with TV standard. Even being multiplied twice, you will get something like 19KHz and still not compatible with TV.
So, the core has 4x of original horizontal freq and about VGA compatible.

kitrinx wrote:I noticed GB runs at 36khz rather than 15khz, like line doubling is always on. Is this intentional?

this is from original Gameboy core. This is not TV console so basically it's not exactly must have TV compatible frequencies.

Probably original author made it as VGA 800x600 core.

Re: FPGA SNES source (srg320)

original FPGA SNES board has 2 RAM chips not in vain. When on-cart acceleration chips are used, they use separate RAM chip.
So, i think this core will use both SDRAM and DDR3. Hope accelerators don't mind of slight latency of DDR3.

Re: FPGA SNES source (srg320)

I didn't say it's not important. It's just too early to think about it.
Core is very unstable and this should be solved before thinking about any features.

Re: Hybrid MIDI Sound Emulation MUNT/FluidSynth

htop is not relevant in this test.
Yes, mouse also have the same route as joysticks and will be affected. So, need to play some games and see if there any additional lag in inputs. You can just play MIDI in background and play some game which has no MIDI.

Re: Scaler

But I just had a thought. You say that half a pixel was cut from the left. Maybe the pixel data starts going to the the scaler too early? I don't know hardware enough to be helpful :( there is nothing i can do there. Scaler gets exactly the same video data as VGA output. You can see that VGA has pe...

Re: Scaler

well, i've checked in old Genesis release which doesn't support coeff loading (20181015) and it has the same issue of cutting top/left pixels. So, if it's the bug then it's inside the VIP scaler, not in MiSTer. This gives me idea that quality of Lanczos PP filter can be improved over standard one if...

I didn't dig too deep yet. I see most chips aren't used now cause i see several internal PLLs but didn't see them in compilation report. So "fun" things are awaiting :) I will probably remove the ability to save backup RAM for now. Currently it's just complicating the port. I plan to chang...

Re: Serial console core. Anyone?

All cores released on 20181118 have UART signals in emu entity. So, just grab sys from any of these cores (Genesis, NES, SMS, Gameboy, TGFx16) Your core needs return correct flags for hps_io: .uart_mode(16'b000_11111_000_11111), so MiSTer will know your core is using UART and will give the option to...
