Re: Master 128 Internal Tube/Expansion Pinout
Nice! 2) Carefully remove the black plug (noting which way it was fitted) Could you avoid this if you removed the Master PCB? Dave Yes but IMHO it's easier to remove & refit the plug than remove the pcb. Removing the plug is easy, just lift the lock tab slightly and then pull up the hold-down s...

Re: Master 128 Internal Tube/Expansion Pinout

Re: Master 128 - obscure video issue?
Hi Tricky, tried latest Astroblaster on my Master - detects SWRAM and loads game - but garbled/rolling screen. <SNIP> Obviously in my case we could have another example of a game that my Master has an issue with but ok for everyone else.

Re: Page values with DDFS rom
ADFS isn't at fault here; it's a consequence of the architecture. You need to ensure your manager ROM is in the highest priority bank for it to be able to disable things early enough. Yes finally someone understands the problem, ADFS isn't the problem (but some people just like to bash it anyway) y...

Re: Page values with DDFS rom
Ok, so, it turned out to be the ADFS rom. It obviously doesn't release all it's work space when disabled. Don't blame ADFS it's your cr*p Megarom that can't disable a ROM properly, try sticking megarom in a higher priority socket than ADFS and it might work correctly. Well I happen to like...... ar...

Re: Master 128 - obscure video issue?
Well I've just copied Frogger from floppy to MMFS on my Master and then run it from MMFS and it works perfectly, sorry but atleast on my Master MMFS does not cause a problem, so I think we can rule out MMFS as being a factor, surely it must be some hardware/timing fault with jnbeeb's Master.

Re: Master 128 - obscure video issue?
I read what jnbeeb wrote to mean he had phyically pulled the EPROM from his machine rather than just unplugging it, I maybe wrong. Until jnbeeb pipes up we won't know for sure...Rich Talbot-Watkins wrote: I would try actually physically pulling out the hardware, rather than *UNPLUGing the ROM.

Re: Master 128 - obscure video issue?
MMFS isn't the issue here, as he says he still gets the corruption when running from floppy with no MMFS fitted.

It's a python script that allows you to downloads videos from youtube, but the best bit is you can choose both the video format & audio quality you want to save.
