Re: Secondary SD Card Access?

Secondary SD Card is accessible only from FPGA core, ARM can't access it and so it can't share it on FTP or Samba. But I do believe after some changes to menu core it could bridge it to ARM and maybe it could be shared when menu core if running? I would appreciate it as I used it for 2 of my cores and it would make my development little bit - if I ...

Re: MultiJoy Support?

Yes, Minimig core does have multijoy support. Evidence is on line 621 of Minimig-AGA_MiSTer/rtl/minimig.v file

Code: Select all

	.portb_in({_joy4[0],_joy4[1],_joy4[2],_joy4[3],_joy3[0],_joy3[1],_joy3[2],_joy3[3]}),

I probably had failed joystick when I tried it for the first time. This is super fun playing Dynablaster with more people :lol:

Re: What keeps changing my MAC Address on reboot ?

I had same issue - each reboot different MAC and therefore DHCP server assigned different IP. After some investigation I found this shell script /media/fat/Scripts/mac_address_change.sh and as I was not sure if I can delete it I "improved" it with single line of code - exit 0 # Version 1.0 - 2019-05-13 - First commit exit 0 ========= OPTI...

MultiJoy Support?

Hi all,

does Amiga core support multijoy? I wanted to play Dynablaster where there is multijoy support in this game (other 2 joystick were attached to printer port via simple wire-only reduction) but I failed to made it work in Minimig.

Does Minimig support it? Have I failed to find it in menu somewhere?

Thank you,
Petr

Ondra works without a secondary SD card too. It needs it only for "Ondra SD" to work - "new age HW" that enables Ondra to load SW fast(er).

Re: Ondra SPO 186 Core for MiSTer

Nice to read that :) I'm not very familiar with Spectrum inside, but I'd say only compatible was Z80 CPU (here U880D - clone from East Germany). It had no ULA. Graphics was generated with 2x i8253 (USSR clone) programmable timers only (except some NANDs and one pulse generator) - so I'd say no, it was not compatible. Unfortunately I can't say how e...

Ondra SPO 186 Core for MiSTer

Hi all, this is my 2nd FPGA core for MISTer - another 8-bit Czechoslovakian computer Ondra SPO 186. It's almost fully implemented - only one missing thing is modern HW called Ondra SD for loading SW from SD cards. Core as it is now is able to load SW from ADC line in and via serial port (user port) with appropriate 3.3V UART converted. If you use h...

Hi all,

thank you for your positive feedback! I'm glad if this core of an old Czechoslovakian computer entertained you (at least for a while).
@Threepwood this core is PMD85-2a (but full RAM mode is not available in this core yet)

Thank you and enjoy!

Hi all, I’d like to share my 2nd Verilog project with you (1st was uninteresting led blinking) – FPGA implementation of Czechoslovakian computer called PMD85 for MISTer. It’s still not 100% done, but it works and you can play some games on it. Here is link to short youtube video with basic and some games for demonstration. https://youtu.be/VVukIzzW...
