I am thining of buying a minimig... and I have some questions:

3. If I buy a minimig now, will I have to update the pic myself (with the serial cable and or that) or it will come pre-installed.[/quote]

Contact AmigaKit - I believe they are reflashing the PIC with the new hex file before shipping.

Don't forget the enclosure for it! :-)

@ Yacube,

Any chance of a 60Hz hacked PAL core option?  I know there we're problems with 1 or 2 programs, but it was stable on the whole.

So in other words, there is no guarantee that my LCD monitor will work with the minimig.... No good :( I dont want any nasty surprises!

NTSC core will work.

When it doubt, go to the manufacturer's website and check the specs.

Just had a request for a location to download Tiny Bootloader.  Here's a link

But if I ply PAL games in NTSC mode, wont that mean that the games will run faster than they should?

As for my monitor, its a Samsung Syncmaster 151s.

@Everblue

According to Samsung Syncmaster 151s specs this monitor can sync from 50 to 75 Hz so you will be able to display scan doubled PAL mode on it. The scrolling will be smooth and games will run with normal speed.

True, there is a slight speedup.  I'm from the UK (PAL) and I moved to the USA (NTSC), but most of my own software was bought in Europe (PAL).  What is surprising, is how much of that PAL software is actually NTSC screen size because it was written for both markets.  Some games even have a PAL/NTSC screen size toggle built in.

I tested a lot of these games using a PAL core, NTSC core and a "hybrid".  Off the top of my head, the only game I actually recall that needed to be run in PAL to avoid clipping was Rodland.

Personally, I keep my real big box Amigas in PAL mode as I like to have the "larger" PAL native workbench displays.  It's not such a concern with the Minimig.

Anyway, it seems that you'll be fine using your monitor with the PAL core.  People need to make note of your monitor, it's a good one!  :-D

What about using FAT32 instead of the old (1988) FAT16 ?

This way you could have 65536 files in root, and you wouldn't be limited to 4Gb SD cards...

Ah, the minimig is looking tempting now! When I have some spare cash anyway. I presume it will work on my TV (it has VGA in).

Excellent work by the people that deserve the praise! What's on the list of existing problems to solve now? Hard file support? 14MHz 68k option (Gunship 2000 and other 3D games would run smoother)? Remaining bugs, if any?

Any images of the "interpolation" feature? Won't this blur sharp parts of the image, or is it done in a non-trivial manner, or like some of the more advanced smoothing functions in software emulators?

Yes, but whether it will work with the PAL & NTSC cores or just the NTSC core is down to your TV.

A few games still have some bugs.  Menace is one where the ship's shield constantly run down which might be due to bad collision detection with teh background graphics.  The vast majority now seem to be running perfectly (as per my list).  Remember, some of the games on that list are still showing as "broken" simply because they haven't been retested using the new core/PIC update.

Personally, I've never noticed anothing because I'm too busy trying to stay alive to examine the screen in any great detail.  :-D

@yaqube

I just tried to compile the FPGA Core in ISE 9.2i (found it for download).
The core was compiled 100% without error (only a few warnings) but Minimig only show a black screen after loading the core.
Do you have any idea what it could be?

FOUR ways:

#1:  Buy a replacement PIC with the update flashed on it.

#2:  Send your PIC to some kind soul who will flash it for you (the chip pops off easily).

#3:  Put Tiny Bootloader and the hex file onto a memory stick, take your Minimig, cable and stick to your friends house and ask him if you can use his PC for 5 minutes.

#4:  Buy a cheap USB to Serial port adapter (link below).

I hope that helps.  :-)
