Re: Genesis / Megadrive core ported to MiST

Hi all, I was keeping track of the Cores and at the moment we have: fpgagen_20181101.rbf - old jt12 (0.4?) fpgagen-titan2.zip - old jt12 (0.4?) and now there is jt12 v0.5 Do we need to check the problem game ROMS with Core fpgagen-titan2 and if that is ok then the changes in fpgagen-titan2 can be in...

Re: Genesis / Megadrive core ported to MiST

OK thanks. I thought it was a general problem. :roll: Same problem on my real MiST and Sony TV with RGB. :angel: i.e. shifted slightly to the left on many games. Does it do it on real hardware? Back in the day I bought a 14" Trinitron and with RGB input selected the picture did shift to the le...

And it's pity that Turrican doesn't start...


I am sure Virtua Racing is like some SNES games (Mario Kart, Pilotwings), it has a special chip inside the cart to perform 3D calculations.

so, you can test in on real genesis hardware?


I have a Megadrive MK1 & MK2 + Everdrive which I can test 'carts' on if needed.

They both have 50/60Hz switches too.

Nice work getting some of those undocumented features working! There is an Emulator comparison video running the TiTAN - Overdrive 2 demo https://www.youtube.com/watch?v=_FyQPn89RZQ I don't know if this helps at all?

Re: Is RGB/SCART blanking signal (Pin 16) too low on some Cores? <1v

So it looks like the default 8mA gives a measured voltage of 1V. For my Sony I have now taken 5V off the TV PCB and via a resistor feed it to Pin 16 so it always forced RGB mode. Then Composite signals were not recognised! so I have added a toggle switch near the SCART socket to Force RGB on/off. I ...

Sorgelig - what is the current set on your Menu Core? As this also drops out with 0.76V being measured.

Is RGB/SCART blanking signal (Pin 16) too low on some Cores? <1v

Hi. I swapped my trusty Panasonic 14" CRT for a Sony Trinitron 14" CRT and I am having problems with it holding RGB/SCART mode. I have narrowed it down to the voltage being outputted in RGB mode on the MiST. For example MiniMig & Amstrad Cores output a measured 1V on VSYNC. 'Menu' Core...

Re: Genesis / Megadrive core ported to MiST

Is the problem that the NTSC/PAL implementation is not fully known on the Genesis/Megadrive? I know the PCB's are the same with jumper switches defining if it is NTSC/PAL and for example on the NES it uses different chips and clock Crystal for NTSC or PAL. I spotted a Youtuber 'Gamehut' he was a Meg...

This scene demo seems to use pretty much every trick in the book even undocumented transparency effects!

A difficult test for the Core! Plus the large cartridge size.

Re: BBC Micro

Regarding White Light I did pop over to Stardot. I went there with the problem ages ago, but checking back today it seems that the blank screen after dying/resetting in the game is due to a file being write protected. This has been fixed and it works on physical disks, however Hoglet (BBC wizard on ...

Re: ATART ST - How to get RGB/SCART

Solved - you need to create MiST.cfg on the SDcard.
As the MiST cannot create the file but it can write to an existing file.

Re: ATART ST - How to get RGB/SCART

It was the 'mono' setting. I changed it but I can't save Core settings?

Is there an Atari ST Core save file I am missing? I have a mist.ini on the SDcard already.

ATART ST - How to get RGB/SCART

Hi,

How do you get it to boot in SCART for use with CRT TV?
If I boot I get angled white/black lines, if I plug into a PC monitor I get a picture. But I would like RGB output
(thanks also for the recent Component Output, although I only have LCD TV's with that option)

Re: SAM Coupe core for MiST

Hi,

How does the Stereo SAM DAC on LPT1 work?

I tried the attached demo - astro2 It gives a list of sound options, if I select '4' which is Stereo DAC on LPT1 I don't get any sound out of the 3.5mm audio jack? The normal Sam sound chip works fine.

Thanks

@Sorgelig - I saw that you updated some of the Core parts (for MiSTER I think).

To save you building the Core I could attach it to a p...

Re: BBC Micro

'Castle Quest' had the wrap around issue and it was fixed but I can't remember if it was on Mist or ZX Uno.

We need to see if the issue is back as it might be Core related. I can try Arcadians on my ZX Uno and see what that does.
