Linear congruent generator, forgot my article from ZX review, oh, my strong point!

In short, scientifically it is called a generator. bad addiction clumsy spectrum. the same congruent according to Knut should look like this for good sequences: 19:17 RAIDER LD HL,SEED LA A,(HL) SUB #8D LD(HL),A INC HL INC(HL) INC(HL) INC(HL) ADD A,(HL) INC HL RRCA RRC(JL) ADD A,(HL) LD(HL),A RET 19:17 RAIDER SEED DEFB 0,0,0 --------------- It was clearly written from a lantern, but it works, be healthy. here is the gene from Special FX (remember them - Batman's, Hyper Active, yes they made a ton of games): 19:17 RAIDER and INC = 1, i.e. odd.Keep in mind that the most significant bits make the most noise, and they take it. those. LD A,H - this is purely my generator. ---------- 19:17 RAIDER Well, I’ll give you more generators, good ones too. here is a generator from Jobby (Jobby, Chase programmer HQ, North Star, Dark Fusion - I talked to him once, very cool dude he gave me a list of his games, I almost fell - monster!!!! he made all the toys alone) 19:17 RAIDER LD HL,(SEED) LD D,H LD E,L ADD HL,HL ADD HL,HL ADD HL,DE INC HL LD (SEED),HL RET 19:17 RAIDER X(j+1) = ((X(j) * A + B) mod R where X(j) is the current element of the sequence and X(j+1) is the next one that we generate so, it’s better when A mod 4 =1 and B is odd. mod - This is the remainder of the division. when we do multiplication as in the example, then what remains in the register after the shift is MOD in its simplest form this is what it is 19:18 RAIDER feel the difference :)))))))))))))) -- State of the Art! Flash inc.
