@bernardoortega well obviously you didn't even try to read arcade documentation and you know nothing about it. Start by reading the wiki

@substring said in Latest upgrade after 4.1:

@Substring Here is the output:

Note that i am not connected to any country VPN here:

Now, i connected to France as example the VPN and this is the results:

Now i can see the update on the GUI and now is been downloaded, so we can confirm a network issue that perhaps some ISPs block the port and not others. E.g same VPN connected to Spain did not work, but the one to France it is.

Thanks for your help to all

Hello,
Simple overclock of the cpu is not enough to handle the dreamcast.
With some custom overclock settings I managed to run Virtua Tennis 2 around 90-95% of its full speed with very few minor glitchs. So the game is playable and enjoyable.
A lot of games are close to work at full speed, if only the pi3 have had a bit more cpu speed.

Every pi are different, so if it crashes or displays a black screen, you must lower some values (see the range in my config.txt below).

WARNING: you REALLY need a good cooling setup (fan + heatsinks) if you don't want to grill your pi.
My settings works for me and my pi3 can stay on for hours, BUT I can not be held responsible if your pi goes down.

In config.txt of the sdcard (plug it in your computer), here are my settings:

kernel=zImage
#old extrem default values
#force_turbo=0
#arm_freq=1375
#core_freq=500
#sdram_freq=575
#over_voltage=4
#over_voltage_sdram_p=6
#over_voltage_sdram_i=4
#over_voltage_sdram_c=4
#gpu_freq=500
#sdram_schmoo=0x02000020

#my custom overclock: cpu / gpu (core & gpu freq should be equals) / sdram / voltage
#arm_freq (1400-1450)
arm_freq=1425

#core_freq & gpu_freq (500-575)
core_freq=550
gpu_freq=550
#v3d_freq (520-530) or more ? under 500 is not enough for the dreamcast
v3d_freq=530

h264_freq=333
gpu_mem=256

#sdram_freq (500-580)
sdram_freq=575
sdram_schmoo=0x02000020

#over_voltage (4-6)
over_voltage=6
force_turbo=0
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4

More significant values are cpu, core_freq and v3d_freq.

Hope this help.
If anyone has a more powerful & stable setup, please share 🙂

Very nice job ! thanks a lot for sharing this 🙂
