A fairly old nostalgia inducing game in the genre of Rogue-Like Turn based RPG. With the addition of an online element.
Can be found here: http://homepage3.nifty.com/rfish/index_e.html

Strangely addicting, and with a very random atmosphere, making difficulty more a thing of pure luck than anything else.
Several starter races (more mod and dev races can be enabled), several starting class paths, and dozens of skill sets, not to mentions spells.

One of the absolute hardest games to play as a mage with the randomness factor as well as limitations with spell casting..

Has a built in wizard mode for debugging/cheating. Though CE works for some things.

*Edit*
Not to be entirely confused with Elona-Shooter, as it's the PC game, which is the fore-runner of Elona-Shooter.
 

PC version: Heres some Buff address codes.
023064D0
023064DC
023064E8
023064F4
02306500
0230650C
023C4494

That's the majority of the 1.22 positive effect buffs, Lulwy's trick, Speed, Hero, Lucky Day, Holy Veil, etc.
Obv they're in 4b, values are also. The address seems to be static.
Gold, platinum, item values (stacks,charges), hp/mp, all 4b.
The official wiki explains toggleable wizard mode with offsets.
I would say This is a fairly good game to learn how to manipulate 4b data in general for basic purposes.

*Edit Bonus* Toggling Wizard mode with CE: Find your # of turns with 4b*1, cntrl+alt+shift+enter, enter offset of CE0. The address changes, 0 is off, 1 is on. Remember to turn off before you save the game, or you'll wind up with the Permanent flag *Debug*.
"CE0" in decimal form 3,296.

Right, so due to some technical errors, I gave some bad hacks on the PC Varient.
The Buff's are not static addresses, instead as many things are in this game, Offsets of your characters # of turns.. Buff's consist of 3 sets(Pairs) of 4byte code.

First is a designation: The type of buff. Lulwy,speed,Hero,Lucky,etc. (Range 1-19)
Second Is Magnitude: The strength of buff. This is the numerical advantage; 70 / 777 on a event producing luck / luckyday. (I'd be wary of going "over 9000!")
Lastly is Duration: How many turns it lasts. This is easily frozen and manipulated as normal.

Shown here in the games save-file editor;

 There are 19 buffs/hex, here are the values;
1: Holy Shield   2: Mist of Silence    3: Regeneration   4: Elemental Shield
5: Speed      6: Slow      7: Hero      8: Mist of Frailness  9: Elemental Scar
10: Holy Veil    11: Nightmare   12: Divine Wisdom   13: Punishment
14: Lulwy's Trick   15: Incognito   16: Death Word   17: Boost
18:  Contingency     19: Luck / Lucky Day

According to the save-file editor, the game supports UPto 15 simultaneous buff/hex's. With the offset range of 1120 to 1296.

Find the value for your # of turns with 4b*1.
Select/Highlight this address/value in CE and hit cntrl+alt+shift+enter. This opens an options box with 3 inputs. We want the rightmost. As this automatically changes the address by the offset you enter.
1120 in Hex is 460, 1121,1122 are respectively 461,462. Or through the same style +1 of the first alteration.
So, we'd have 3 per buff that are T for Address of Turn,
T+460 with value of 1-19 for type,
T+461 with value of how strong the buff is(Typically 60-999),
and T+462 with a value of Duration (1-999)

Though, it's worth noting, that the highlighted address/value is ex-changed and the original does not remain in the selection box, so it would be wise to get as many "pairs of 3" as buffs you intend to use of your initial address/value.

If it's not clear as mud now, let me know how to clean it up. Cheers and happy gaming.
