- • Cheats − Here are some cheats for various games. (I suggest that if
- you do any of these, you do not use the original disc, but rather work
- on a copy. Ed.)
- 4.04
- Cheat for Minerva’s BattleTank If you run the following program you
- will have however many lives you specified at line 20:
- 4.04
- program segment missing
- 4.04
- Cheat for 4th Dimension’s Inertia - Type in the following and then each
- time you lose a life, you won’t!
- 4.04
- program segment missing
- 4.04
- Cheat for 4th Dimension’s Man-At-Arms − The passwords for the 3 stages
- are: INCUBUS, STRANGE and PULSARS
- 4.04
- progam segment missing
- 4.04
- When you run this program, it will allow you loads of lives, punches and
- lots of energy. Be careful not to set any of the variables at &FF
- because it does tend to make the program crash!
- 4.04
- Cheat for Minerva’s RedShift − Once the game has loaded, type the
- following:
- 4.04
- PHASING GERALD
- 4.04
- Note: When you pressed <11>, the screen will change to the Help screen.
- Take no notice of this and keep typing the rest of the words in.
- Remember that there is a space between the two words!
- 4.04
- If you have entered this correctly, you will hear a bleep. Then just
- press <1> or <2> to play the game and when your Energy is low just press
- <E> and you’ll see the energy level is full again! Also, when your
- TurboEnergy is low press <T> and you will be back to full strength!
- 4.04
- Cheat for 4th Dimension’s E-Type − The following will give you as many
- minutes as you like to get round each track:
- 4.04
- program segment missing
- 4.04
- Type in the above and you’ll have all the time you want to round each
- track! Mark Faulkner.

- • DOS RAM Disc − In DOS, it is possible to set up a RAM disc and indeed,
- for many applications, it is vital to do so if one does not have the
- luxury of a hard disc. Regular DOS supports a maximum of 640 kbytes of
- RAM, although we did learn about Extended Memory in last month’s
- Archive. The problem with a DOS RAM disc is that the memory is actually
- taken from the 640k system RAM. At least it certainly is with current
- versions of the PC Emulator.
- 4.04
- A few months ago, an application appeared on the magazine disc called
- !PCRamDisc. This made use of the fact that the PC emulator can support
- up to two “hard disc” partitions and that one of these could be in the
- Archimedes RAM disc filing system. (In fact one of these can be on an
- ADFS floppy!). In this way, a large RAM disc can be used within DOS
- which does not take anything from the regulation DOS 640k. This seemed
- a really good idea and I was eager to try it out.
- 4.04
- The program which produced the DOS partition is a variation of the Acorn
- program to construct a hard disc partition but with the filing system
- and paths changed and with the allowed partition sizes also changed to
- more convenient values. Having created such a partition, the !Run2 file
- must be modified to tell the machine where the partitions are.
- 4.04
- Then, when the emulator is run, the new “drive” must be initialised
- using FDISK and then formatted using FORMAT. This part really annoyed
- me as I had to do it each time I used the emulator, and I kept for
- getting what to do.
- 4.04
- It seemed a good idea to create a ready-formatted and initialised
- partition before entering the emulator. I am sure someone could write a
- program to do this, but not me. Obviously, it would be silly to store,
- say, a 2 megabyte partition in readiness; this is just a waste of space.
- However, I discovered that an initialised, formatted, but otherwise
- empty DOS partition of one megabyte capacity could be compressed to just
- over a kilobyte using Archimedes ARC, a Public Domain file compression/
- decompression program written by David Pilling.
- 4.04
- On the magazine disc there is an application called !PCRamDisk (note the
- different spelling). This contains a compressed but empty DOS partition
- which is decompressed into the RAMFS before invoking the PC emulator.
- Please read the !Help file before using it as the !Run2 file of the
- emulator is overwritten when the application is run. Brian Cowan.
