As far as I can see, ALA42's tool covers quite a few
Either by LOSSLESS (code swapof one code onto another, preserving the code used as the swap strategy - in Liteon, you need Omnipatcher to do this)
Or by editing the code name of the strategy you want, to the code of the media you want it applied to (and if that code already exists, edit it to something else).
Ask Liggy/Herrie and others about the NEC (one of the few where you can make, or at least MIX strategies).
Though the question remains, WHY?
Code-swapping is NOT a universal panacea!
If the drive is well tuned, media should work well on the correct code.
For some drives, code-swapping is usually used as a trick to gain extra write speed - the massive overclockability of lower speed "RICOHJPN" being the best example - media made as quality 2.4x, that can take far more.
For other drives (Liteon!) it has been used to rectify strategies that clearly do not work - the fact that some "popular" swaps are now being retired is a good sign.
Finally, adding/overwriting a code (often a similar make/ID) can often allow a media that's not coded in the drive, to work better than at default strategy.
Ideally, good media on good drives should not need tampering with.
Equally, bad media is bad media, and bad drives are bad drives, and no amount of tinkering will make a silk purse out of a sows ear.
