MiSTer FPGA Forum

I would need to see some lag test results before buying a device like that. Even the expensive Extron units introduce lag.

I just got an email saying the Ultimate Spinner PRO was back in stock. Clicked the link and already out of stock?

The Amiga core could really use this, IMO. Its positioned so far out compared to other cores!

Here's a particularly egregious example (VideoKid):

Notice that it is significantly shifted downwards, whereas normally on the Amiga you get a slight shift to the right:

Unfortunately no one seems to care about this. Kind of mind boggling that fundamental stuff like this goes unfixed.

The folks over at the English Amiga Board kindly helped to fix this. Simply change the .run file to this:

Saves:WHDSaves/MyGames/ReshootProxima3/rp3.bin

Tried that, with and without the quotes, and get the error: "Unknown command. failed returncode 10".

Also, I can not get the screenshot to display correctly in AGS:

I tried saving compressed and uncompressed from GIMP2 and Paint Shop Pro 6 but still same result.

edit: fixed this issue, needed to save as 8-bit

I have the latest MegaAGS installed on my MiSTer. Can you please link to the instructions on how to add a new game to it? I just bought Reshoot Proxima 3 and want to add it to MegaAGS. The game has it's own HDD installer, but obviously that will only install to a new folder, not MegaAGS.

About the Video Timing option in this core - does this only affect the vertical screen size / refresh rate or is game logic also affected by this setting? E.g. does the game run slightly slower at 50Hz compared to 55Hz?

Thanks. I've raised the issue there. Hopefully it gains some traction as I feel this is an important issue.

Yes, I assume it's a system-wide problem, but I have only tested on the two arcade cores I listed. Which repo would be best to raise this on?

It would be a big shame if this goes unnoticed as it's something that MAME has nailed for decades, and is clearly undesired behaviour.

Yes, it usually freezes on the slide for me too.

The freeze doesn't occur when the bats spawn, it only occurs at the point in stage 5 that I posted a photo of, and it only occurs in versions (i.e. most of them) which do not have the excessive bat spawing.

Any idea exactly what Extron units I would be looking for that supports h / v position and h / v size? Presumably I need something that keeps all signals in the analogue domain or there is going to be lag introduced due to digital processing.

This is almost certainly something related to your TV, as there is no feedback channel from a CRT back to the MiSTer, so MiSTer has no way of knowing that you've done anything to your CRT (and thus cannot modify its behaviour on that basis).

If that was the case, then why are non of the other cores I tested affected?

Overscan being difficult / impossible to implement is understandable, but it would be nice to see hori / vert adjustment settings in all cores. It would also be nice to see the max values of adjustment levels being increased too, as -7 to +7 isn't always enough to get the position right.

Would that be the jtframe_resync.v module? How difficult is it to change from 4-bit to 8-bit values? Haven't some cores already done this? I'm sure I've seen some that allow for values > 7

It seems that most of the arcade cores actually have these options, it's all the other cores (console, computer) that don't.

This seems like such a fundamental feature that I am surprised that so many cores are missing it. Are core authors just not aware that there are many people using old CRTs or is it down to something else? E.g. limited memory, etc?

I managed to get ADFFS installed onto an HDF HDD image. Instructions on how to do it can be found here (see sirbod's first post):

https://stardot.org.uk/forums/viewtopic.php?t=9246

However, it was mostly a waste of effort as hardly any of the protected games I tested worked on the Archie core.

Does anyone know how I can copy the ADFFS zip file from Arculator HostFS to my HDF image (both within Arculator)? I tried copying the zip from HostFS to my HDF image, but ArcFS will not open the file, even if I change the ADFFS zip type to DDC (ArcFS).
