Darrin: What hardware add-on ? Will this HW add-on be something specific to dennis' design, or possible also with the Illuwatar ITX version of the board ?

There's a link to it here with some details.  It will fit into the PIC socket on the "Dennis" v1.1 board.

I don't know about the ITX board.

Well, the manual says it's suitable so there's absoluetly no reason to expect anything different.


I have checked the manual. It says vertical frequency has to be between 56 and 75hz.

Isnt minimig 50hz (or 49.9 to be exact) at PAL mode?

This is the link for the Samsung 151s manual.

Yes, the unhacked PAL core needs 50Hz.

By that link it certainly needs the NTSC core or the hacked PAL.  However it states:  "Design and specifications are subject to change without prior notice.", so earlier ones might have been different.

I didn't enter that model myself (only Samsung I own is a multisystem VCR and a digital camera), but I'm sure I checked online when you asked either in a online manual or on a online shop's specifications page (Tiger Direct, Newegg, etc).  The manual in the link does not look familiar.

If in doubt don't buy it.  It's kind of annoying now because I don't know whether to trust what has been entered or go with the manual.  I think I'll change it to PAL = NO to be safe.  It makes me wonder whether it may have been tested by a user with the 60Hz PAL core without even knowing it.

If you have that monitor at home then stick to the NTSC core (but try the PAL).  One thing I discovered when testing all of those games is how few are actually PAL only (Rodland is the only one that springs to mind), some have a PAL/NTSC toggle while the rest are obviously NTSC when viewed on a PAL screen as indicated by the larger border at the bottom of the screen than the top.

One of the advantages of the MiniMig's size is that if the store will allow it, you could take the MiniMig with you and hook it up before you buy, if they have the model of monitor/TV on display and plugged in and they have an extra outlet for your power supply.
How are you helping the Amiga community? :)

@denli on 2008/9/30 14:38:22 & mini minimig

I've always dreamed about being able to develop embedded products around Amiga. Mini minimig would fit in that space pretty nicely.

1) Amiga68k development tools available
2) powerfull for many needs
3) if PAL/NTSC video out is possible, then home automation & information via un-used analog TV connectors, with astounding multimedia effects (all TV broadcasts are now digital here in finland, so analog TV band is totally free in the *ss of a TV)
4) because it has audio out it could do also networked music playback @home
5) it could speak automa"g"ically (alarms, greetings, information etc...)


What it needs extra is 10mbit ethernet adapter in those extra FPGA pins.  :-)

I went ahead and ordered a Minimig :)

Meanwhile I am preparing a folder with .adf files... I have 5 main qustions:

1. Is the filename for .adf files limited in length?

2. Can I use subfolders (for example put multi-adf games in 1 subfolder)?

3. I have noticed in the game compatibility  list that there is version '080408'. What does this mean?

4. In case that my TFT doesnt do 50hz, I could run the games in NTSC mode for 60hz... How do I do this?

5. Is it possible (just wondering) to use an RGB/SCART cable with minimig for a normal TV?

Anything else I should be aware of, please let me know :)

thanks!

No, but due to FAT format is advisable use the 8.3 format for filenames (8 chars for name and 3 char for extension)

Quote

2. Can I use subfolders (for example put multi-adf games in 1 subfolder)?

Not yet. Maybe in future releases of firmware it can be done, meanwhile all files must be in root directory.

3. I have noticed in the game compatibility list that there is version '080408'. What does this mean?

I think that it refers to firmware version, but I'm not sure. The last one (done by Yaqube) is the most compatible and feature-rich.

4. In case that my TFT doesnt do 50hz, I could run the games in NTSC mode for 60hz... How do I do this?

Just use the NTSC core instead PAl core (I didn't try it because my TFT supports PAL core).

5. Is it possible (just wondering) to use an RGB/SCART cable with minimig for a normal TV?

No, the Minimig only has a VGA video output.

Hope it helps you...

Hmmm alright.... but:

1. Will i have to reflash the minimig once I get it?

2. Will all games support NTSC?

Thanks!

Excellent.  :-)

Yes, it is 8+3 characters max (eg. "ELITE.ADF" or "RODLAND.ADF").  However the name can be longer but it will be displayed as "ALIENB~1.ADF" instead of "ALIENBREED1.ADF" and take up the space of 2 files.

So, I highly recommend you name your ADFs something short to fit into the file format.

Also, the files don't list alphabetically when you put them on the SD card, however Jacub wrote a nifty program to run on the PC which will shorten your ADF file names for you and sort them into alphabetical order.

PM me with your email address and I'll send it to you.

Quote
2. Can I use subfolders (for example put multi-adf games in 1 subfolder)?


No.

However, you can have subfolders for storing extra files in.  I keep the old cores, different Kickstarts, etc in folders on the SD CARD.

The equivalent of changing your Amiga's ROMS on a Minimig is dragging the ROM image you want out of a folder and into the root directory of the SD Card.

Quote
3. I have noticed in the game compatibility  list that there is version '080408'. What does this mean?


That was the core released by Jacub on 08/04/2008 with ECS and floppy write support enabled which I used to re-test programs that had previously failed.  That's why you can see the same program listed more than once.  It allows you to see which programs wouldn't work initially and which ones now do.  If Jacub releases his dual floppy core for Xmas then you'll start seeing games tested with "122508" (Not that I believe this will happen - it's just an example).  

Quote
4. In case that my TFT doesnt do 50hz, I could run the games in NTSC mode for 60hz... How do I do this?


Jacub releases each core as separate PAL and NTSC files.  Put both in a folder on our SD card and then copy the NTSC one to the root and boot the Minimig to see if everything works.  You should see the Minimig initialize and the "floppy hand appear".  Load a game and make sure everything works.  Now, replace the NTSC core in the root directory with the PAL one and try that.  If you get a picture then your Monitor supports 50Hz and you can stick with it, otherwise just put the NTSC core file back in the root.

5. Is it possible (just wondering) to use an RGB/SCART cable with minimig for a normal TV?


Depends.  As long as the TV supports the refresh rates then you'll be OK.

Anything else I should be aware of, please let me know :)

thanks!


I always keep a copy of my SD Card on my PC.  Be aware that your Minimig is just like a real Amiga.  If you load an ADF image that has a virus in the boot block then you'll infect the Minimig - but it won't write the virus to the SD Card.  Now, if you swap ADF images using F12 while infected then the virus could write itself to the new ADF.  I had this happen just before I left home where a virus from (I think) "POW" took out my bootblocks on Speedball2 and Rodland (Rodland had a virus checker that warned me it had happened).  Fortunately all I had to do was copy the uninfected ADFs from the PC back to the SD Card and to make sure that I switch the Minimig off after playing POW and before loading another game.

If you have any questions then feel free to email me and I'll be happy to help if I can.

Also, there's a support site at www.minimig.net.

No. The minimig uses 2 files:
    -minimig1.bin: put it in the root of the card. There are 2 versions of it PAL and NTSC.
    -.hex file: is the file to flash the PIC

So, to change PAL/NTSC core you only must copy the right minimig1.bin in the card, but no flash the PIC.

2. Will all games support NTSC?

Since I only use the PAL core I don't know if all games works in the NTSC core. I think that you maybe loss some of screen's botton in PAL games... but I'm not sure.

Sorry! as Darrin says there's a 8.3 limit in order to avoid the ~ symbol in the filenames.

@DARRIN

Wow, thanks for the very extensive reply - I'm truly and utterly impressed.

I am hoping in a few weeks I will be contributing to the games compatibility list!

If I remember well many PAL games did not go down on the screen all the way, so my guess is that with NTSC mode, those games will fill the screen nicely. Games making use of all the screen would have the bottom bit chopped off.

One more thing - I formatted the MMC as fat32, is that ok?

I'm on a mac.
