• There is no battery indicator
• You can't watch the CPU temperature
• and you can't set the CPU frequency governor

Of course you can use gkrellm for the first two but it does not play nicely with dynamic window managers like wmii. If I wanted to drag windows around I'd use Gnome, thank you. It is much nicer to change the right side of the status bar to show current temperature and battery status. 

Beware! This change is for the sh script version of wmiirc. If you are using the other version this may not work.

In file: ~/.wmii-3.5/wmiirc change the part that says

# Status Bar Info
status() {
        echo -n $(uptime | sed 's/.*://; s/,//g') '|' $(date)
}

to

# Status Bar Info
status() {
	BAT=`acpi -b`
	LEFT=`echo $BAT | cut -d ',' -f 2`
	TEMP=`acpi -t -B -c | cut -d ',' -f 2 | cut -d "." -f 1`
	LOAD=$(uptime | sed 's/.*://; s/,//g')
	DATE=`date +"%d/%m/%y %R:%S"`
	echo -n T: $TEMP '|' B: $LEFT '|' $LOAD '|' $DATE
}

You can of course keep the longer date format by changing "$DATE" to $(date) but I like it shorter.

Now on to the Frequency Governor! You can download the script below and put it in ~/.wmii-3.5 . Don't forget to make it executable.

cpufreq @ SymbolEngine

Now when you run the cpufreq action you will be asked for your password. This is because CPU governor can only be changed by root user. After that you'll get a nice dmenu on top of the screen to choose a governor.

I hope you find these scripts useful.

You need completely steady hands, eagle eyes or a stereo microscope, a really good tweezer to grip the tiny resistors, a soldering iron with heat control and a good quality soldering& paste flux. I had& none of them. After 2 hours of agony I could only solder one (1) resistor into place. Then when I accidentally touched the one I soldered when I was trying my luck on the second one, the first one came off… Complete with the original resistor on the DTV board. Talk about pain.

I left everything on the table and fired up my a1200 to normalize the levels of stress hormones in my blood.

The other day I decided it would be much easier to take the original resistors out and solder new ones in than to try to piggyback them. And here it is, the turning point:

Spiff's page says these resistors should ideally be 165 ohms. What I had in hand was the 220 ohms resistors I prepared for the easy fix. The ones on the board where 680 ohms, so I decided to try my luck. 220 ohms is much closer to the ideal value than 680. I soldered them in and as I thought it was much easier.

The result is as anyone can guess, not as good as the original fix, but is much better than the original buggy board. It would have been much better if I had resistor with a closer value to 165 ohm. So I dub this fix Half a Spaceman Spiff's Ghetto Color Fix, or HaSSGCF.

So the moral of the story boys and girls is, it's much easier to replace SMD's than to solder them piggybacked if you don't have right tools.

I'll add my experiences doing these hack here somewhere when I find the time to do them.  

1- Fix the colors:

    PAL version of the DTV is cursed with a buggy video generator. White is not white at all, and some colors are very hard to distinguish. If you don't like your DTV with ghetto colors, try spacman spiff's easy colorfix: (scroll down to easy and better fix)

Spaceman Spiff's DTV colorfix

Note: I have tried this hack with limited success. You can read about it here.

2- Build keyboard and IEC (Disk drive) ports:

     DTV unit has all the needed pins for connecting a ps/2 keyboard and multiple daisy chained disk drives. If you are going to do any serious hacking you need these ports.

    There's also a faster way to transfer homebrew software into DTV. Dtvtrans by Daniel Kahlin lets you transfer files from your PC to DTV using a special cable that connects your PC's parallel port to DTV's joystick port.

3- Install DTVMON & DTVBOOT:

    Now that we can transfer files to DTV and we made it into something more than a toy we need to get rid of automatic booting into game menu.  This software lets you configure boot behaviour, get screenshots, run a machine language monitor, run dtvtrans without entering the bootstrap code into basic and some more. It is a pretty useful piece of software by, again Daniel Kahlin (This guy just loves DTV, and we just love this guy) :

DTVMON & DTVBOOT

   You are going to need Kahlin's Flash utility if you want to write DTVBOOT to DTV's flash rom and believe me you will:

Amiga 600 PDF Schematics @ Symbolengine

I hope you find it useful.

Amigaguide to HTML converter @ SymbolEngine

1. Go to settings/system menu on your GP2x
2. Make sure the IP Address is 10.1.0.1
3. Turn on telnet, ftp, samba and web servers (You wont need samba if you are using a real operating system)

If you are running Linux:

1. ifconfig usb0 up 10.1.0.2
2. now you should be able to ping the device with:
   ping 10.1.0.1

If you are running m$ windows (Who said windows is easier to manage?):

1. You will probably need USB Gadget driver for windows. Most flavors come without it. Download and install:
   Download USB Gadget Driver for Windows @ M$
2. Turn on your GP2x. A baloon will pop up (don't you hate them?) to say connection is established. 
3. Go to Control Panel -> Network Connections.
4. Open TCP/IP properties of "Linux USB Ethernet / RNDIS
5. Manually configure it with an IP of "10.1.0.2" and a subnet mask of "255.0.0.0"
6. You should be now able ping your device from command shell with:
   ping 10.1.0.1

Now you can also telnet to your GP2x, transfer files with samba (means: windows file sharing) or ftp.

There is also a pretty complete web server with even PHP installed running there. PHP I tell ya! Have fun!

Alternative:

Companies do not pay huge amounts of money to develop new copy protection schemes that don't work and admit the fact that data on any media will always be copiable, no matter what anyone does, just like the Beta or VHS tapes before them. Because they don't pay for encryption schemes, media becomes cheaper. More people would like to buy original HD-DVD or Blue-ray discs because everyone likes to own the movie they like in its original package. Some people still copy, but they always do anyway.

Just give up the ridiculous fight!

Amiga 600 Schematics also available.

Pros

• Inexpensive storage
  SD cards are really cheap nowadays and they are easy to find. A 1gb sandisk that costs about 15$ holds all the HVSC archive and all my games and still have 500mb free space. 

• Really fast loading times
  Faster than 1581, 64hdd and ide64. Actually the only thing it cannot beat must be a cartridge =)

• Cheap, cheap, cheap
  Considering the other options, this is the most cost effective modern storage solution for c64. Shipping is also cheap because of its:

• Small size
  It fits in a standart C= cartridge case. It just needs to be slightly modified to make an sd card slot. It is pretty light so you dont have to put something underneath the cartridge for the fear of breaking the edge connector.

Cons

• Closed source and slow moving firmware
  Documentation is scarce. The firmware is being developed by a single guy, Oliver Achten. While it is a big feat of programming it slows down the process. 

• Mostly readonly access
  The only tool that can write to sdcard is a floppy reader. It reads the inserted disk and converts it to a d64 format file. There are no other software i know of  that can write on sdcard.

• No 1541 emulation
  And this means no fastloaders, no multipart demos. This is really a big downside. 

Last Words 

MMC64 from Individual Computers surely is a big step forward on the way to eliminating long loading times from increasingly hard to find media. Even though the hardware is working really well, I believe the available firmware is far from complete and  an opensource model should be considered for firmware development. All in all MMC64 was a great buy for me.

If you also happen to have a Retro Replay cartridge "MMC64+RR disk image mounter" allows you to mount d64 images from your SD card. Many games are known to work with this setup:

MMC64+RR Disk Image Mounter @ CSDB

If don't happen to have one fear not! For there is "Sasq's alternative BIOS" that can  load some ide64 fixed games.It's not as compatible as the former but what can you say?
