Re: Internet and Linux Shell for Amiga and ao486

For purposes you described current serial connection cannot be used. It's bound to internal hardware serial port which goes to ARM side and has no external pins. You need a special version of Minimig which will output serial connection to GPIO and thus will allow to connect different kind of externa...

The ao486 core has been written specially with worst CPU implementation. 3D graphics hasn't been included for the same purpose - make users to suffer and cry.

To bring up the menu you can either die or press start to bring up the inventory screen and press up+a on controller 2 from the inventory screen. Inventory and number of deaths will be saved.

What exactly saved in Legend Of Zelda? I guess it's not like Action Replay memory dump/restore when you continue play from exact saved state? This save is some kind of legal save from Nintendo as i guess. So what is saved? Hall Of Fame? As I see from the code, the saved memory has fixed size and onl...

Re: USB Hub board

Here the first board that I did yesterday night. That took twice the time that I expected (you have to be extra careful soldering the FE2.1, its pins are tiny). It's better to solder LED15 (power). It's not simple power LED - it's ON only when USB hub is initialized. So, it's kind "OK, it work...

Re: USB Hub board

The board can be used as a standalone USB hub as well. You can see 2 additional holes on the edge without USB connectors. These holes can be used to fix the cable in place.

Re: Would MiSTer ever be able to run a Neo Geo core?

Well, DDR3 should be more suitable then. Still many games require more than 32MB according to your histogram. Graphics and audio use sequential access and pretty easy mapped to burst access to hide the latency. I don't know architecture of NeoGeo carts, but since they have separate buses for each de...

Re: MiSTer Case at shapeways (nylon plastic)

Connection points make sense for shapeways orders where every small detail costs a lot. And if you order panel without holes, then later you will need to order again - will pay a lot for panel + shipment. With connection points you will order one panel and then later will decide depending on future ...

How about other way for closed holes: Make a several connection points around the hole? About case: I guess it's not XS version, right? Also i see the second bottom inside the case - not sure how it can fit the USB board. I have the MiSTer with USB hub board next to me - its height may be twice low ...

Re: MiSTer Case at shapeways (nylon plastic)

@NegSol what do you think about making I/O board holes covered by thin plastic originally? So, user will decide what hole to open depending on addon board. For example, user may have no I/O board originally, but still can use XS case without holes. Later he can get I/O board and will open the holes....

Re: Would MiSTer ever be able to run a Neo Geo core?

Ok, after checking the Wiki, NeoGeo is pretty much similar to Sega Genesis by architecture. Total 224KB RAM can directly fit into BRAM, so no complex shared access is required. I don't know how big are NeoGeo cartridges. Wiki tells about up to 800Mbit (100MB), but i think 99% of games use not more t...

Re: Would MiSTer ever be able to run a Neo Geo core?

so, if it works on DE1, then it will fit in DE10-nano as well. Though need to check about the RAM. Basically DDR3 is pretty fast if used in burst mode, so it depends on core design. MiSTer has 3 types of RAM: BRAM, SDR SDRAM, DDR3 - so even if one type is not enough, then combining these 3 i believe...

Re: Joystick testing thread

New MiSTer update automatically detects the analog range, so it should be compatible with more joysticks without special tweaks.
Probably Daptor 2600 will work as well.
